In the spirit of traveling with kids, here are some of my favorite links to keep little hands busy during travel. We will be making some of these things for our summer trip! Monster Crayon Roll: From the Iowa Farmer's Wife - So Cute
Playdough Filled Balloons: From Play Create Explore - You could also fill with rice, beans, or cornstarch. Great idea!
Toddler Time: Busy Bag Series: From Second Story Window - Some great ideas!
