3 hour car ride with a 9 month old? Any advice?

I took my daughter on a 8 hour car ride when she was 8.5 months to visit family. It really was not as bad as I imagined it was going to be. Just bring some of her favorite toys, some snacks (if she is eating finger foods), have some music on and have mommy or daddy sitting in the back with her if able to. My daughter slept for the majority of the drive and I made sure we made a good number of stops to give her a break as well. It won't be as bad as you think!
