How exciting instead of a booster seat what about a carry case and tether the care case into the back seat they will curl up and go to sleep together. I bought a really nice pink one and used it alot for my babies when they were little. Great for Vet trips and outings when they are tiny. It will make them feel safe as well.
And for potty a pee pad in the well of the back seat one on each side when you stop for coffee you can let them out on the floor for a run about and a pee. Sounds like so much fun can I come LOL LOL |
