13 mo old twins hate the car seat.

I am all of out ideas here. My twins (13 mo adjusted) absolutely hate the car seat. They're okay once we get driving, but getting them in there is taking years off my life. They stiffen like boards, thrash, twist, scream. When you finally get the one in, the other does the same 🫠

Does this end?! Is it a phase? Am I going to die a premature death?

The only thing that helps is handing them a snack when we put them in the car. I'm worried about creating bad habits there but I also need to, like, survive.

Any tips?
