Road trip with 7mo

We’re going on a 6hr road trip with our 7mo and need tips! She usually doesn’t fall asleep in the car 😞 I’m thinking of buying a movie on my phone so it can keep her distracted since we won’t have connection for most of the trip. I was debating on buying baby food but in all honesty I’m SUPER paranoid and would prefer to make my own but I don’t have any of the pouches 😭 any and all tips are appreciated!
