My DS2 has had gastroenteritis and had stopped eating solids now he is starting to eat again he keeps biting when it comes to nursing his last BF was at 5am and he would normally have had 3 more. He may be teething as well and has bitten me in the past but never refused the breast he just clamps then bites and starts screaming at me when I pull him off. I need to express now and will see if he will take a bottle of DP. Could it be he is full as after eating too much?
