DD has been sleeping in her carseat almost exclusively since she came home. She tends to urp when on her back, and choke on it, and gag, and not sleep well. We haven't been brave enough to try back sleeping again yet.
So for the first two weeks or so, I would put her in the carseat drowsy and she would nod off on her own. Then we had Thanksgiving with lots of family, OS, OT, and lots of people holding her. Then the three week GS. It got harder and harder to put her down. Now she has to be completely out, which is usually 20+ minutes, but can take up to 40-50 minutes sometimes.
She will start falling asleep and be relaxed for like 2 minutes, then she just opens her eyes really wide, then needs to grunt and stretch out and change positions and just wakes herself up more. Then I have to rock or bounce her, or let her pacify on the breast, and if milk comes she gets really frustrated. Won't take a paci, or my finger. Hates, hates, hates the swaddle. She just grunts and stretches until she works up into a frenzy. We basically wrap her loosely in a warm blanket and tuck it away from her face when she's asleep. I can't do this anymore, but I don't have any ideas for helping her settle in the carseat. I just can't get to anywhere to pat effectively.
