DS is 5 months old. When he's upset or first waking up from sleep, his immediate reaction is to grab a hold of his face and scratch the holy bujeebuzz out of it. Currently, it looks like a cat went to town on it because I was sleep training last week. It's just not light stratches either, they're fairly deep gashes! I've resorted to putting newborn gloves on his hands at night to prevent further damage. His face looks terrible and it breaks my heart because it looks painful!

Any advice on how to prevent him from doing this? When did your LO stop scratching at their face?
