Car seat drama

I've posted before about my baby resisting getting in his car seat. It's worse after daycare when I'm alone. We always go home and nurse and he naps on me. So I think he is getting upset that I'm strapping him down in a seat away from me. He is not sleep trained. We co sleep and I feel like anytime he is near me all he wants to do is nurse all day fed or not (bottle of pumped milk and food). I can't take it much more. The car seat is the worse because my post partum anxiety is at an all time high that time of day. I feel like he has an unhealthy attachment to me. And I've tried getting him a bottle while in seat on way home In case he's hungry. It worked for a week and now he just swats the bottle and throws it.
