Quoting Poяcelain:" Don't give up! Just express some and squirt a little in his mouth. If you are engorged it is difficult for him to latch. Keep trying and he'll eventually get it."
OP try this and try out some different latching holds. Look up the football hold latch and see if that helps. He is new to breastfeeding so he is learning as well as you :]
^ That is the football.
Don't give up mama. He will get it down soon. He is still very little.
^This link has some pictures of different types of latches and how to do them.
