What moms are saying
Last month I ordered your summer co-op box...it's life changing!!
I just have to tell you that I'm SO glad I found your account! We've found your printed preschool playbook curriculum in which I pull activities frequently, but last month I ordered your summer co-op box and let me tell you...it's life changing! Being able to open the box and just have everything prepped and ready has seriously been amazing. My 4 year old asks to open the box every single day and do an activity. Thank you so much!!
I'm so glad I found you and your boxes!

THE PRESCHOOL PLAYBOOK
Little ones won’t stay little for long. Spend intentional time together and teach them even at your busiest with the help of one magical book.
Guide them in the big world with over 300 wonderful activities—in arts, science, math, and even cooking—that only take 2 minutes each to prep and are a lot of fun to do.
Reach milestones together every single day with The Preschool Playbook.
Do you need to buy The Co-Op Box and The Preschool Playbook together?
No. Both are nice to have, especially if you’ve got active kids. But they are two separate products that do not rely on each other. While they offer the same style of activities, they differ in the number of activities and the level of DIY you have to do.
The Co-Op Box has 21+ activities and comes with all the materials you need prepped and ready for you. You’ll just need your own scissors, glue, and markers. The Preschool Playbook, on the other hand, is filled with 300+ activities, which require you to provide all of the materials and do the prep work.
What age range is this for?
The Co-Op Box is perfect for kids between the ages of 3 and 5.
When will the subscription be sent out?
All pre-ordered subscriptions will be sent on the first day of each quarter (January, April, July, and October). If you order after pre-orders are sent, your package will be shipped the next business day.
How often will the subscription renew?
Your subscription will renew on the 15th before the new quarter (March, June, September, and December).
