A curated environment for children to learn, grow, and explore through sensory and motor play.
We believe that play is the most important work of childhood. Here's what guides everything we do at Otto:
We play with a purpose, thanks to experiences that are proven to support growth and development.
We view the five senses as a playground for connection, play, and development.
We encourage playing pretend, leaning into fantastical themes, and experiencing the world as limitless.
This is a place for you to gather and grow with like-minded families. Welcome to your village.
Our activities are building blocks for gross motor skills that kids will use for a lifetime.
For 2 to 5 years old
Sensory adventures for ages 2 to 5. Each week brings a brand-new world to discover, inviting toddlers to move, explore, and grow their motor skills, confidence, and social connections through hands-on play.

"We were amazed. This is the first time she's playing it by herself. We are just standing back and observing."
"When we first came to Otto, Kayla didn't even want to take off her socks. The team at Otto never pushed — they created such welcoming, intentional spaces that gave her the time she needed to watch, wonder, and eventually step in. Kayla's comfort and confidence grew here, and so did ours as a family."
"We did six sessions and every single one was a new kind of fun. Hailey got to play with mud, water, ice, paint — all kinds of textures and colors. One of our favorite moments was seeing her so brave during a little 'camping walk' — stepping over pebbles, branches, and grass like a tiny explorer."
"We drove an hour from San Ramon to join — and it was totally worth it! The setup and activities were so creative and unique, unlike anything we've seen before. Our kids had a blast, and we as parents loved it too."
"Each session feels so thoughtfully designed, with creative themes and beautifully prepared props. When we first started attending, he could only crawl. Now he is running around, and I feel like he has grown alongside the sessions."
"This is our first time handing our daughter a knife… and she's doing quite good with it. We should trust her more."
Join us as we develop a love of learning through play and exploration.
