I have seen posts everywhere about busy bags. I did this earlier this summer for our boys and it has worked out great. I grabbed some pencil bags from Target and filled each one with something different. These are in my A Team van for traveling.

These are great for travel and tossing in D's diaper dude. Maybe I will get creative and make some games for them
