He doesn't do it very often and I had kind of forgotten about it until today when I went to give him a drink and saw tooth marks in his arm.
He must have bitten himself quite hard because the dents have gone but there are still little purple marks.
Is this normal? Could it be teething (I know he is teething but he has never bitten himself before that I am aware of)? Stress (DH has been on shift for a few weeks now and perhaps he's picking up on the fact that it's stressing me out?)?
Any advice would be appreciated smile
