To the moms who breastfeed, I need some advice. My son is 3 weeks old and just started latching a couple of days ago. I am using a small nipple shield cause he wont take the other one at all. Anyways, he refuses to latch on to the right side! I have offered it first, and last, and he just wont take it. He will only latch to the left side. Does anyone know why hes doing this and is anyone else's child do this, and any advice on how to get him to latch on to that side?
