So my DD has been attacking her head and face in her sleep or a while. We've clipped her nails, tightly swaddled her and even have to hold her arms down if we catch her. Problem is I can't watch her 24/7 especially when I'm asleep. She breaks her swaddle within seconds by rocking and rolling over. I can't give her mittens because she sucks her hands a lot and I don't want them getting sore. Basically I'm asking 1) is this normal and 2) is there any way to stop it?
