My son has a temper -- and he freaks out during diaper changes (has for a few months). Rolls over, wants to play with stuff on the tape, wants to try to stand on the table. If we do it on the floor, he flips and craws away. Diaper changes take 15 mintues.

This morning, he was flipping and not letting me put a diaper on him. He is so strong!! I finally looked at him and said "NO" very firmly. And then he cried. I feel badly!

How young is too young to discipline? My son is 10 months.
