Mine does it too, also on her forehead. I cut her nails every few days otherwise she looks like she has been in a fight. She started doing it over a month ago, she is 7 months tomorrow.
Same with my lil boy he does it so much :(
My boy does it too :( we cut his nails twice a week but he still manages to make himself bleed a bit sometimes :( He does it when he is tired and when he is stirring just before waking up (which I can't really stop now that he sleeps in a separate room, he hates having his hands covered so weve never than mitts etc)
Thank you everyone ❤️ it does seem like a self soothing thing but I'm the same, I feel like I'm constantly cutting her nails so she's not covered in cuts!
My boy does this on the top of his head when he's feeding as a comfort thing... And he did it a bit on sides last week but seems to have stopped. Maybe teething related possibly?
