Car seat situation

Hello everyone!

I’m a FTM and I have a 2 month old baby boy but recently I have been having some problems with him staying in his car seat.

I have only put him asleep because it’s kinda the only way but once the car starts moving 10 minutes into the ride he wakes up and starts crying and in the car is a lot more difficult to calm him down.

So I would love to hear from y’all on what I can do since I wanna get on time to his appointments and or go grocery shopping at least 😊
