Across country toad trip with new baby!

My husband, new baby and I are driving across country this summer with our camper trailer to spend the summer with my family. When we leave in June our baby will be about 9-12 weeks old and the drive is 54 hours total so about 5 days drive depending.

Wondering if anyone ever drove this far with a young baby and how it went? Any survival tips? 😅 we are planning stopping to feed, change n stretch about every 2-3 hours or as needed. We also have out two beloved dogs. I’m hoping everything will go ok!!!

Any traveling advice will help
