Anyone else baby have teeth since 2 months old and had to deal with biting and was able to get over it to continue breastfeeding? He's currently 4 months old and I have had to deal with him biting me since 2 months old. Most people don't have to deal with this until baby is a little older so they understand more at 8-10 months.

I have tried saying no nice, saying no while being upset. I have tried pushing my breast so he can't breath for a second but I feel like he's too young to understand it hurts to bite my nipple. He just similes and thinks it's funny or cries. Any other suggestions for a baby that's younger?
