My Kids LOVE it!!! Just subscribe you won't regret it.

We have been getting these kids for probably 2 years now and my kids are SO excited every time!! They are always fun activities and, while somewhat messy ;) that's part of the fun, and it's never hard to clean up. They are always some great sensory play and great opportunities for them to be creative. We started when my son was 3 and he is now 5 but we are going to just keep getting them since his little sister is now 2 and loving them also. Even my 8 year old wants in on all the fun so I think they are really great for any kid in those age groups. Bonus, the owner Robin is SO sweet and has been so helpful when we needed to change addresses, renew etc. I can't recommend these enough!

Expertly Curated Kits!

My 3 year old daughter and I loved exploring our “Outer Space” kit on a snow day. I appreciated that the kit includes color-coded materials and instructions for each activity, along with easy STEM talking points and questions to discuss while you’re doing the activities. The activities are thoughtful and quick to keep a toddler’s attention but also open-ended to encourage their exploration and curiosity. I also love supporting a mom’s small-business and mission to encourage messy play!
