N.H.
Gingersnaps! I get motion sickness and have two daughters who get it as well. Gingersnaps provide the 'dry' that a sick tummy needs and ginger is known for it's 'anti-nausea' attributes. I like Trader Joe's brand. Also, if they do get sick, the best thing I've found is to keep a coffee bag (the kind you put fresh ground coffee in) in the pocket of your child's door or where you can reach for one quickly. They're just like airline sickness bags but more readily available. When I'm travelling with the kidlettes and they use a bag, I can pick one up at a nearby grocery store!
