I'm not sure if it's anything more than a stage they go through, but I remember when my girl went through it. Oh how those little baby nails hurt. It didn't matter how often I clipped them.
I felt so bad for her the day she scratched herself.
I know this is different because aly is older...But lucas used to scratch his face (cheeks) a lot from about a week after he was born upto 3 months ish. I dunno why they do it? His skin didnt look dry but I put different creams on it to try stop him scratching, incase it was really itchy, not just a habit he got into. (sounds weird I know) other times I wouldnt put anything on it, and he still scratched. I had to keep his nails really short, which you should do anyway cos of all the bacteria you get under them, and kept something on his hands most of the time. Mittens were too big...Or just didnt stay on so I ended up using baby socks on his hands! That worked and everyone thought it was cute lol
Brayden still does this and he's almost 9 months old, sometimes he'll scratch the fabric on the couch because he likes the noise, and other things because hes just feeling it. Sometimes he'll scratch me but I dont think he means too, it's normal girl no worries.
Chu scratches his mattress at night and it drives us nuts!!! We moved his bed into our room because i'm a paranoid nutzo and his scratching in his sleep wakes us up but he stays asleep when he's awake he scratches us and the couch pretty much anything he can reach. His doctor says that it's essential to developing coordination. I guess that I could see how that's true but I can't wait for him to grow out of it!
