My 9 month old son is always tugging at his right ear. So much so, it irritates the skin behind his ear sometimes. It started just before his first teeth came through at 4.5 months. Then it stopped for a while. He now has 8 teeth (4 bottom & 4 top, all front) but he continues to do this. At first I thought it was developing into his “I’m tired” signal but he has been known to do it as soon as he wakes up after a full nights sleep. He isn’t showing signs of illness, increased temp or ear infections either. Could it possibly be more teeth? Why is my baby tugging at his ear?
