Mummies my LO is 5mth old. He always like to rub his face until it's red and always end up scratching his own face till bleed. And he often rub on his right ear too. When will his rubbing action ease off or is this something normal?

then possibly might be dry also. oh another thing does he lie on a certain position for long period? that might also be the case. blood flow back when he move so there is a sensation. quite alot of possibilities. if it is not rash. Maybe try apply body cream or aloe vera for him first. see if it helps
