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?

My daughter previously did similar actions. Went to the PD and he said there are dirt/mucus in the nose and babies doesn't know how to get it out so they tend to rub their face. You may want to check your LO's nose when he starts rubbing the next time. :)
