Best day care I can ever imaging. Very caring team and clean environment for kids to play and rest. It provided bilingual education to my kids, they were able to learn both mandarin and English. Lunch and dinner are provided. Many toys to play indoor and outdoor. I can't imagine a better place to send my kids to. read more

Sending our two children to Dian Dian Daycare was the best decision we could have made. The staff is incredibly reliable and professional, ensuring every child receives individualized attention. They provide healthy meals, maintain a consistent daily routine, and foster excellent developmental progress. Most importantly, our kids absolutely love going there! read more

What a hidden gem! So blessed to have found Dian Dian Day Care for our kids! Both of my boys went to DianDian from 2021-2025, and left the day care because they turned 3 and started preschool. They are 26 months apart, and overlapped for a month at DianDian. As first time parents back in 2020, my husband and I were both super nervous about putting our son in daycare. We toured around 10 day care centers, and finally decided on DianDian; even though it was completely out of the way for us, as we lived in downtown SJ, and later moved to Los Gatos. We have never considered taking the boys out of DianDian. Let's start from the beginning! While searching for daycares for my son, as I was going back to work soon. We came across DianDian. I wanted my son to go to a place that has a clean environment, responsible staff, and focused on academics, Mandarin and music. DianDian checked all those boxes for us. To our great surprise, this would also become a place where my kids felt at home, and the staff became their second family. Michael was extremely responsive when we tried to schedule a tour. While on the tour, he explained to us how much he cared for all the kids that came to him, and it was plain to see with all the holiday cards hanging on the wall from previous kiddos that went there, many cards were sent after the kids stopped going there. It felt really good to see all these families still kept in contact with Dian Dian after many years. I was impressed with the individual beds he had for naps, they are proper beds instead of the stackable cots that most day cares have. They are so much more comfortable for the kids! Also Dian Dian feeds the kids three meals a day plus home made snacks! It was almost unbelievable to hear! Other day cares charged much more monthly, and only fed lunch. My kids loved the food they served. Often they'd get seconds! It's so convenient for us not to worry about packing food for day care. Dian Dian took care all of it! Throughout the day, there are many different classes scheduled for the kids: music (Michael plays many instruments), fun activities that focused on practicing fine motor skills, English (with a hired licensed teacher), story time, nursery rhymes, etc. I was so happy when my son came home and repeated a rhyme he learned to me perfectly! They also cooperated with us potty train our kids. They have these individual child sized urinals and toilets, it's really nice to have the kids get familiar with these while potty training. I have not seen that at other day cares. The backyard has been converted to a padded playground, with slides and tunnels. My kids loved playing outside. They also teach the kids to clean their eating area, I was surprised to see my kids do that at our own dinner table! It was very cute! The hardware of a day care is important; but to us, the attitude, work ethic, and the willingness of the staff to work with parents was the most valuable. With over 30 years of early childhood education experience, Diandian day care has been a tremendous resource for my husband and I. In my own journey as a mom, I have leaned on Michael as a mentor on how to discipline, teach, interact with my kids. I have learned so much from him. Michael was always so patient, not just with the kids, but with my husband and I as well. I'd ask questions like "He is not listening to me! What should I do?" "How should I discipline him?" "I am about to pull my hair out!! What should I do as a parent when I am mad?" etc. I will be forever grateful for everyone's help at Dian Dian. My younger son just started preschool yesterday, and the last two mornings, he has been crying to go to Guan Yeye jia (Dian Dian). Makes me feel so comforted to know both of my sons have spent 2 years each at a place that they treasured. Where these early interactions lay such an important foundation for their education and social lives later. Michael called me this morning to ask how my son was doing, I was so very touched. I wish all the teachers were like Michael, Mama Hong, and Yan. They are truly an amazing group of educators and caregivers that you can trust. I know I will always trust and love them. read more

My daughter had a great year at Dian Dian. The owner couple and the teacher are experienced educators in the field for 20+ years. They have their own education philosophy and we fully trust them with it. My daughter is a later talker by CDC standards and she had her first word just 2 months post joining Dian Dian. Fast forwarding a few months, she can sing many many Chinese children's songs and rhymes and carry a full conversation thanks to Guan Yeye, Nai-nai and the teacher, Yanzi Laoshi. She maintained a healthy weight-gaining trend and often said that she loves Nai-nai's home cooked food. Kids there all nap in a proper crib in a dark environment which helped my daughter feel at home during nap time. We never had to worry much about her - Dian Dian made it so easy to trust them with our precious daughter. Not a single time that she came home with a dirty diaper, diaper rash or a hungry tummy. Occasionally when my daughter had "accidents" and they even washed the soiled clothing for me. There was 1 time both me and my husband had to work late till 7PM so we asked Dian Dian to help, and they were so flexible to provide help in circumstances like this. I have endless good things to say about Dian Dian. We have now moved up to a large preschool in Cupertino and looking back we have 100% made the right decision to start with a reputable home-based daycare like this. read more

I continue to trust Dian Dian. During covid-19, they have stepped up safety protocol and ensure hand washing and temperature monitoring. Kids do not need to wear a mask inside. I appreciate how warm they are to my kids. That said, my child has not brought home arts and crafts and I learned the kids do have tv exposure. It is not every parents ideal but they keep kids active regardless. read more

My previous reviews were filtered by Yelp. I am reposting. Posted 1/7/2010: This is an update since my March 2009 post. My daughter has moved on to preschool in the Cupertino area, but we kept in touch with the owners of Dian Dian. My daughter asks about them from time to time. One of the owners, Michael, visits my daughter once or twice a month at her preschool and often times he brings her favorite homemade bun. She absolutely loves the attention! I think that is the kind of love and care that is hard to find. I feel very fortunate to have found a daycare for my daughter when she was so young. I was reluctant to put her in a home based daycare because I've heard many horror stories. But this was not the case at Dian Dian. As you can see in the pictures and you can also see during a tour, that their facility is very clean and feels like home. They have REAL beds and cribs... not rolled out cushions or sleeping bags. The only reason I moved my daughter to preschool is to get her exposed to a big school setting. I believe Dian Dian has about 10-12 children in their care. In hindsight, the small number is a good thing... there is certainly more attention given to each child. I will not go into great lengths about my daughter's current preschool, but just to show you the difference between the level of care -- she came home with poop stuck up her butt today. Not a care was given to just wipe her clean when she couldn't hold on to the poop any longer. There was also her dirty clothes stuffed in a bag, which sounds decent, BUT when I opened it there was a lump of poop inside. Ok... the decent thing a preschool teacher can do is to flush the poop away and toss the soiled clothing in a bag. At Dian Dian she ALWAYS came home clean, appropriately dressed for the weather, fed, and happy. Posted 3/3/2009: My daughter has been going to Dian Dian Daycare since she was 12 months. She is now almost 3 years and can speak better Mandarin than my husband and I combined. In addition to the foreign language skill, she learns the alphabet, basic arithmetic and Chinese nursery rhymes/songs; eats healthy homemade meals; drinks fresh-squeezed juice and smoothies; plays & sleeps in a clean and safe environment; and receives a lot of love from the caretakers. The owners/caretakers are CPR/First Aid certified, a Christian family, and used to own a restaurant. I did my homework before choosing this home based daycare center. My mind is always at ease when I drop my daughter off in the morning. I'm extremely satisfied with my choice and would recommend them to anyone who is looking for a daycare center for their precious child. read more

Both my kids spent a bit over a year here at Dian Dian. The little one just moved on to preschool last December and would still tell us how much he misses Michael baba, the owner of Dian Dian. I took the kids back to Dian Dian to say hi and he was all in tears when we were leaving and just wouldn't let go of Michael baba. This just tells us how much love my kids have received from Dian Dian. Thank you Dian Dian. read more

What a wonderful home daycare! Highly recommended! Super warm and caring family daycare that will truly take care of your little one as if he/she was their own. besides the amazing care and attention, my favorite part is that they feed your little one three meals a day (breakfast, lunch and dinner) what an amazing additional perk for a busy working parent! Love Dian Dian and our son will really miss it when he "graduates" soon! read more

My son was with Dian Dian for a year before starting pre-school. It was definitely a warm and caring environment for toddlers. The owner of the day care showed a lot of care to the children. They provided a day bed or a crib for every kid, unlike most day care centers where kids nap on nap mats. There are toilets for small children. And the day care well supported potty training. The playground in the backyard was recently renovated, which was a large, nice extension to the indoor play area. In addition, kids were often strolled to a nearby park to enjoy outdoor activities. I could tell the quality of care by seeing how eager my little one wanted to go to Dian Dian every morning, and how much he missed the care providers after leaving the day care. Highly recommend for parents seeking childcare service for toddlers. read more

Our daughter has been going to this daycare for almost 2 years now. The owners/caretakers are great and definitely go above and beyond the call of duty in caring for the kids. They are amazingly patient and very understanding. It is a home-based daycare which adds to the personal touch. They speak mostly Mandarin so it's a great way for the kids to learn Chinese. They have steadily improved upon and added to the facilities over the years so those are top-notch as well. I'd give them 10 stars if I could. read more

First, I am a regular yelper and not a one time poster as a previous reviewer mentioned. Second, I am very protective of my 1 year old son and want him to be in a safe environment. After interviewing many daycares such as happy daycare and kiddie academy, I chose Dian Dian because they treat each child as if they were their own. The other day care employees looked like lifeless zombies and had no passion. Mr. Guan, who is full of passion, truly knows how to "train" children and is a miracle worker. I trust him more than myself with my precious son. He even teaches my husband and I how to build better habits for our child. Afte sending my son to Dian Dian he has improved so much on his speech, napping habits, and eating bigger portions. A previous reviewer mentioned how they did not feel comfortable with having 10-12 toddlers in 2 rooms with 3 adults... Saying it was not safe or dangerous. In Dian Dians defense, Mr. Guan does a great job "training" the children and they are all synchronized... They play calmly and are under control. Having 1-2 adults watch the children while one cooks the food is not a problem. Hence why they have been open for 10 years. Recently, I even noticed there are actually 4 adults now. Another winning factor is Dian Dian is only daycare I found that makes HOMECOOKED and HEALTHY foods. I refuse/despise day cares that give children cheese, crackers, pizza, sugary juices, etc. If you are mandarin speaking, know what a REAL healthy diet is, don't mind a small/not so fancy place, and wants someone to love your child as much as you do... Dian Dian is for you. read more

This is an overdued review. My son has graduated from Diandian and moved to a day care center about 5 months ago. Our experience with Diandian is all very positive. When we moved to this neighborhood, we have made some arrangement with another family care at first. My son cried harder and harder during every drop off/pick up. The owner complained about my 20-month old cannot feed himself well and cannot nap well and pushed us to withdraw. (Fact #1: she wanted to admit an infant which would bring her more income. Fact #2: She does NOT care about the kids, it is just a business for her.) I immediately started to look around and found Diandian based on friends' recommendation. What a difference! Diandian did everything to ensure an easy transition. Texted me updates and pictures of my son's activities there during the first week. No more crying! And what's more important, I can tell my son has developed the bonding and trust with Diandian. Looking back, what are the most important factors for us parent when looking for a daycare? Safe and Caring environment. Diandian has both. My son was nurtured there. To him, it is another home. All the other things are bonus, like reciting all cute lyrics, good routine, flexible on hours, etc. I give it 4 star, as to me, nothing is perfect, not even us parents or our own home. But if you ask me whether I would recommend Diandian, YES, absolutely! read more

We love this daycare! The care providers/owners are caring, understanding and thoughtful. They truly care about every child there. My 21-month -old son is very shy and they always look out for his best needs. They even purchased a small cod for a bigger child who is about to move up to a preschool, so that he will get used to sleeping on it. They have two awesome separate play areas for infants and toddlers and tons of toys my son loves a lot. This day care is only a couple of minutes away from a park, where they have a lot of outdoor activities in the park when weather permits. They not only take care of children's basic needs, but also teach. My son can count to 1-10 in English and sometimes up to 100 in Mandarin. He also knows shapes, colors, and a lot of Chinese children rhymes. It is really fun to watch him "show off" what he's learned at day care. We also like nutritious meals and healthy snacks such as freshly squeezed juice and home-made yogurt they provide each day. All in all, we highly recommend this day care to parents who are searching a safe and caring place for their precious little ones. read more

My husband and I are high achievers, having attended the Naval Academy, MIT, Stanford, Columbia University, and UCSF between the two of us. That being said, it was important for us to find a GREAT daycare for our young daughter. I echo other reviewers when they say that you will not find another place with the same level of care and attention (and love), then at Dian Dian. My daughter ate well (they serve 3 meals daily), slept well (they have actual cribs and beds), and played well there. They are flexible and accommodating (they don't charge you if you're running late). We don't speak Mandarin at home, but my daughter can speak because of her exposure to the language there. So if you're looking for your child to learn Mandarin, definitely consider this place. read more

Great owner and the highlight of this daycare is it's 2-3 min walk away from a big park and they have necessary safety means i.e., seating kids in a big cart to take them to the park of 2-3 min walk to play offering the kids a great opportunity to have a much larger / natural playground. This is one for the key reasons we choose DianDian. We enrolled out kid at 1 year 7 month old and later happened to know my colleague also sent her kid to DianDian before going to a preschool after potty trained in DianDian (and quite happy there). And another highlight is as a parent you don't need to worry about kids food during the weekdays as the owner ran restaurant before and can and know how to make great food. After my kid left and went to preschool we also had some occasions sending kid to DianDian to help out. Strongly recommend. read more

My twins have been going to DianDian since they were one and a half years old. A few months ago when they turned 3 upon DianDian's advice sent them on to preschool. To be honest we are still questioning and lamenting on this decision we've made and wishing we should have kept them in Dian Dian for longer. Unlike some other parents, we have never experienced kids' reluctance to go to Daycare. Instead they are always happy and excited about being able to see "Michael Ba Ba" (DianDian's owner and teacher) everyday. Sending them to school is easy for us. Once they stepped into the Daycare door they would quickly run in to join the fun and sometimes forgot to say goodbye to us at the door. I feel that the little ones very much felt loved and safe in the Daycare. They were fed well too with home cooked, nutritious meals three times a day. As parents we had little to worry about our kids' wellbeing as long as they go to DianDian. I am always amazed how much energy Michael has and how much patience and love he has for kids. Same with Hong (Michael's wife). It would take that kind of strongly loving, faithful personalities to succeed in cultivating such as loving home away from home for all the kids. My kids turn out to be loving, happy, confident, high-energy and free spirit little human beings, and fluent in Mandarin, thanks to the effort and love Michael and Hong invested in them. Believe me, you won't ever regret trusting your kids to DianDian's care. read more

My son started going to Diandian when he was 1.5 year old. He stayed there a little bit over one year. The reason we decided to leave the daycare is that my new company is very far from Cupertino and traffic is not good on 880/280. We are happy with the way Dian Dian care of my son. The owner is very professional, considerate and helpful. My son likes going there everyday and made several good friends. The food is healthy and the sleep room is much better than other family cares I visited. One time my son got some virus, had to stay at home and did not want to eat. When I called Michael in the morning he asked me to come over to pick up the lunch since my son may not like the home food when he was sick. We truly appreciate his consideration. There are some previous reviews concerned that the play room is small. Yes, it is not big. As I observed, the inner room is for some kids for special care. When my son just joined, he did not like to sit for long, even 5 mins. He was in the inner room to play with the helper and watch other kids in the other room. When he can sit quietly with other kids, he sat on the little stool to take the class. They do go out everyday when weather permits. There were couple times I met them in the park when I was jogging there. There is no formal curriculum. As I am concerned, my son's health and happiness are the most important at this age. My son kisses Michael when he leaves the daycare everyday. Overall, we are satisfied and will recommend to friends. We will visit them again and may need their help during winter and spring breaks. read more

This daycare center is clean, spacious, bright and all-in-all a cheerful place for the kids. it is the most convenient place to send your child while you are at work. Another thing, the owner used to be a restaurant owner and a lot of kids are happy with their meals provided! read more

Unfortunately, my daughter will turn 3 in September and will be graduating to preschool. I'm concerned that we'll have to lower our expectations for the next facility because Dian Dian has been that superb. read more

I was shopping for a home daycare and I couldn't find the one where I can feel comfortable with. I found Dian Dian and I liked it because almost all the house is dedicated to the facility, a room with little beds for the ones who walk, other room with cribs for crawlers, other for eating and teaching, two more rooms with toys and space to play, and the backyard, a lot of toys. They speak Mandarin all the time, and I speak Spanish at home. I think my son is the only one without Chinese background, but he understand what they say to him, and I like the fact that he is expose to another language. They are open to listen my requests about how I want things with my son. Finally, I think the three poeple who take care of the babies enjoy their work, and their time with them. read more

My kid was in DianDian for 2 years, he graduated and moved to preschool recently. We like this day care a lot. Safety was the first consideration when we selected daycare, and Dian Dian was really paying good attention on it, my kid never had an accident in DianDian during the 2 years he was there, and after he joined new pre-school, he had 6 accident reports within first month, this makes us really miss DianDian a lot. The details of settings in DianDian (low beds, small toilets, etc) also show how much the owners care about kids. Teachers treat each kid patiently and nicely, they make different kinds of food for kids, and provide flexible drop off/pick up hours that really helps a lot for working couples. I also like the clean environment Dian Dian provides, they regularly wash the toys and boil the utensils. I would highly recommend this daycare to anyone! read more

My daughter is always happy in Dian Dian. Daycare facility is nice and clean. Kids are taken to a local park almost everyday. Dian Dian care-givers treat every child as their own. They are exceptionally professional, and with a strong personal touch. My daughter has been much loved and well cared for. After six months of being at Dian Dian, she had to move onto a preschool. Saying goodbye wasn't easy for everyone. We will definitely miss Dian Dian. read more

My son has been going to Dian Dian daycare for over a month now, so far he is doing well. He still hasn't come home with diaper rashes or bruises/scatches, which was one of the many problems with his previous daycare. From what my wife tells me, they do try to teach the kids numbers, animal names, etc... and spends time on teaching behavior problems - such as no pushing or hitting. I like their facility because they delicate a lot of space for the kids to play, a lot of toys, and small sinks and toilet designed for toddler's size. I also like the fact they speak only Mandarin Chinese - so my kid can pickup the language, especially since my wife and i don't use it at home and their brains are like sponge at this stage. There are 3 adults in the house, so the ratio is about 3 to 12 most of the time. I'll update once my son is completely settled in this place in the next few months. So far, I am recommending other parents to tried them. read more
