My 2.1yo DS2 has started biting his nails. He does it most of the time when he's not actively using his hands, in particular in the car, in the buggy, during any story time, lying in his cot at bedtime, which watching cartoons etc. When I notice I move his hand out his mouth and just tell him to stop biting but of course he keeps at it.
He'll also pick at his toe nails too but not as often, as I guess usually they're in socks and shoes.
Shall I ignore and not worry or try to do something to stop him? Anyone else had this this young? DS1 doesn't do it neither does anyone else in the family.
Silver lining is that at least I no longer have to trim his nails
