The teachers and staff are attentive, caring, and genuinely invested in the children. We also really appreciated the strong sense of community Happa creates for families. They organize many events and opportunities for parents and children to connect, which made it feel like much more than just a childcare center.
We’re thankful for the teachers and staff who were part of our daughter’s early years and for all the love and care they showed our family.

My family and I joined Happa Baby in January of 2026, when my son was 7 months old. Happa Baby was the perfect location for his first daycare. They were so kind and patient with us as new parents navigating they scary new idea letting someone else take care of him. They treated our son with so much love and care, we never worried about him and were delighted everyday with the photos of the sweet memories made with his classmate. I'm so grateful for all the time he spent in sloths class with all of his teachers but especially Teacher Winnie. The way she took care of our son and helped him to grow respect for his classmates, build his fine motor skills and language development was incredible. When we had to change daycares due to a move, she displayed for us how much she truly loved our son and had been a huge part in raising him to be the strong wonderful toddler he is today. If you are looking for a space that has dedicated loving teachers, extremely communicable and thoughtful administrators and beautifully clean and organized facilities then you have found the right place. If we could have stayed till TK we would have, the administrators went out of their way to make us feel welcome and plan events to help all of the parents build a strong community. My family and I will miss so much about Happa Baby but most of all the staff that made it feel like a home away from home for my son.

We enrolled our daughter at Happa Baby School when she was just a baby, and it's been a wonderful experience! The baby class was so nurturing and really helped ease the transition for all of us. One of my favorite things has been getting the daily pictures and videos. Seeing her smiling, crawling, and exploring always made me feel connected and reassured throughout the day while working.
The classes are very well-kept, and once our daughter moved into the toddler group, meals were provided, which has been a huge help. The outdoor space is also fantastic with plenty of room for the kids to explore and play safely.
The hours are fantastic for working parents, and Carol and Maegan have been incredibly responsive and supportive, especially during transitions or changes. We highly recommend Happa Baby School!

Vicente Planells PalopLocal Guide · 140 reviewsiTotal number of Google reviews Vicente has written across all businesses on Google Maps, not just this one.
I cannot recommend this preschool highly enough. From the moment we enrolled our daughter at eight months old, our experience was nothing short of exceptional. It's a truly special place that combines a nurturing, family-like environment with a high standard of care and education.
The caregivers are outstanding—they are patient, kind, and clearly passionate about what they do. They provided age-appropriate activities that kept her engaged and stimulated, fostering her early development in a fun and creative way. The center also offers and prepares the food and snacks that are given to the kids.
In addition, this is a Chinese immersion preschool. Even at such a young age, my daughter was consistently surrounded by the language through songs, stories, and daily interactions. Finally, they use a dedicate phone app that allows you to contact the director or teachers as well as follow all the different activities that teachers set up for the kids.
For any parent looking for a warm, engaging, and culturally rich environment for their child, this is the place!
Price assessment: Reasonable price

Our twin toddlers started attending Happa Baby in September 2024 at 2 yrs old and have had a great experience at HB, both at the old and new locations. The teachers like Wu Laoshi and administrators like Carol and Megan made their transition from a nanny to preschool as smooth as possible. They've made lots of friends and learned alot of Mandarin. My wife and I have also enjoyed getting to know the other parents as well, and there's a great community that is active outside of school hours. The facility is large, nice, and convenient for dropoffs/pickups. Also, the hot lunch and snacks provided by the school are nutritious and a big time saver for busy parents.

We have had a great experience sending our daughter to Happa Baby for the last year. The teachers are very caring and patient with the kids and the school makes sure to create a warm, open environment for the children as well as families. There’s a good balance between structure, learning (Chinese and English), creative play, and outdoor time. Our daughter is developing just as we’d hope, been able to keep up her Mandarin (after we lived in Taiwan for a year), and has made really close friends at school. We feel lucky to have found Happa Baby and recommend it wholeheartedly!

Our 18-month-old has been at Happa Baby since last year, and it has been a wonderful experience. He has grown to adore his caregivers and teachers, lighting up with excitement every time we arrive. The team at Happa Baby provides a nurturing and safe environment where he can explore, learn, and grow with confidence. They offer homemade, nutritious meals every day. The genuine care and attention they give children truly set them apart. We couldn’t be happier and highly recommend Happa Baby to any parent looking for a loving, supportive space and great parent community!

My daughter has attended Happa Baby for the last few months in the infant room! She loves it - she has learned a number of new things there: crawling, sharing, and has grown noticeably more independent and social.
The teachers are wonderful, all very kind towards her, and even ones outside of her class know her name. Carol & Maegan are very involved in the day to day operation of the school - and we’re extremely helpful with us while we transitioned her in.
Overall, we have been so happy we sent our kiddo to Happa Baby!
