Hello everyone! I have a question for you. My baby is three months old…

Hello everyone! I have a question for you. My baby is three months old and I notice that he spins his head a lot at night. I try to put him on his back, but I put a small pillow under his back, but he still manages to turn over on his back. Because of this, I'm starting to lose hair all around my head. Can you tell me what it could be and will these little hairs grow back in these places?
