Bring toys she's never seen before. Buy things for each child.
Make a trip to the Dollar Store & buy some fun (quiet) new toys.
(Inspect them for rough edges....some can give quite a cut).
-Doodle board (hand held)
-deck of cards (for the older kids)
-coloring books/crayons (older kids)
-I love small hand-held toys. Make sure they have a button to make them quiet.
-Favorite blanket for the little one
-Some Matchbox cars
-for food: pretzels, protein bars for sustenance (yummy kind), goldfish, some cookies, Halloween size chocolate candy, bring 3 empty water bottles (the kind you buy prefilled) so you can fill up w/water if you need to, graham crackers, cheese sticks etc.
-Take a walk down the aisle w/your little when when you need to
-magazines for and geared towards your 7 & 5 year olds
-iPods for the older kids w/headphones
Have a safe trip!
