What do you do when your baby hates the carseat? He would cry and scream every time we put him there. Any tips?

Could it be that the straps are too tight? My cousin had that issue and my niece stopped crying after that was adjusted. Otherwise, some of my friends suggested singing to the baby to help soothe him, or having some soft toys (like cloth books) to help keep him distracted (but nothing too small or hard that could end up being a potential choking hazard). Good luck!!
