I took an 18-hour trip with my little guy when he was a year old. I sat in the back with him a lot and showed him videos of animals on my phone. He's almost 2 now and my other son is 7.5 months and we go on long trips all the time and they just sleep for the most part. They're actually easier than our 2 middle school aged kids. It's not too hard. Pack a cooler of squeeze foods and snacks, lots of room temp bottled water and formula, and when baby gets fussy, it's time for a pit stop. Let him/her play around and get out some energy, change the diaper, have some chit chat, snack and a bottle. I think you'll be surprised at how easy it is. The hardest part is packing all the crap you might need.
