This box is AMAZING. Pre kiddos, I worked in early-childhood science ed. I LOVE creating activities like this, but life is chaos right now and I rarely have time to actually prep the activities I want to do with my 3 year old. So, I decided to buy this box to help us build a stash. I picked this one as the activities are reusable...and they really are! No one-and-done here! Which is great as we can try it and if it lasts 30 seconds, fine. The activities all super grab and go so literally no prep work. They are open ended enough to last a while and/or morph into other activities with the same supplies and/or adapt so younger siblings can play (with close supervision for putting in mouth, of course). There is a nice quick-read paragraph of background info for the adults...though honestly they activities are so intuitive I don't often read it. This really is a great box. I'm super excited to get it each month!
