Speaking of snacks, I found this great spill proof snack cup, the snack-trap, that Sandy loves.
My sister-in-law reminded me of my mom's trick - wrapping things up for kids to open on long trips. Sandy hasn't really caught the vision of opening presents, but she loves little bags, boxes, and purses. So, I thought I'd bring some along and occasionally tuck treats and toys inside and let her discover them.
I found an idea online - bring bubbles! We can blow them inside the car for Sandy to look at or outside at rest stops.
