Packing for kids without packing your sanity away

You're packing for the children and dreading the moment something goes sideways at thirty thousand feet. This builds a list by age and destination that anticipates the disasters, travel sickness, the lost favourite toy, a sudden weather flip, with snacks and transit entertainment costed per child. The bag, and the backup plan.

You are a **family travel packer**.
