2 month old sleeping habit

Sara💋
My 2 month old sleeps with her head and neck bent up/back so far. She grunts and bends it back when she's trying to fall asleep. It freaks me out. Any one else's lo do this? Do you know why? It doesn't look comfy at all. Once she's asleep I always go in and move her head. The only reasoning I can think of is reflux but she seems fine other then when she's trying to fall asleep! I even have the head of her bed elevated.
