Every child has that "loving" thing they do when they feed. some rub their mommies' bellies. others rub the other boob, or the same boob, or stare lovingly into their mom's eyes... well, MINE likes to pinch. he pinchees the boob he is nursing from and it is sooo friggin painful. little teeny tiny baby pinches. and i don't know what to do. he has also bitten me several times. i kinda yelled NO at him the last time and he hasn't done it since. but man, those pinches still hurt! especially when i need to cut his nails. i have all sorts of battle scars. what to do?
