Aside from lugging a carseat, carry–on bags and other items of entertainment with you for airplane travel, a savvy mom knows to cover her bases on the food front, too. The challenge is keeping all the necessary items in one easily accessible place so when the tot starts to amp up, you can settle him down with a quick fix of raisins or Cheerios.

The Packin Smart ($20) stacking tower makes it a cinch for moms on the go. Take one for a quick jaunt to the park or stack five together for a long trip with your youngster. For infants, the dispensers can hold formula, baby food, and dry cereal for longer trips. Each container comes equipped with a lid, cap, and base and is dishwasher safe.
