Traveling with 1 year old...help!

Dawn

We are about to take our nearly 3 year old and 1 year old (as of May 1st) on a roughly 10 hour road trip. I’m not as worried about my 3 year old because I can occupy him pretty easily. But I am nervous of what to take along to entertain my 1 year old. She’s not a big fan of car rides in general and I’ve been trying to think of thinks that she could do on her own in the backseat to keep her occupied. Any suggestions or tips are welcomed!!!
