So, let me start at the beginning. My son was born with a heart defect that required surgery a few days after birth. I wasn'table to nurse him after birth, but a few days after birth I was able to non nutritive nurse him before his surgery (I had to pump first). They didn't want him getting to much food in hs belly before the surgery. After surgery the Drs were very concerned about him getting enough calories so they required him to have bottles so they could measure his intake. Luckily, i didnt have to supplement with high calorie formula because they tested my milk had more calories than thr formula (yay!) They let me beginning nursing a few days after surgery, but only a few times a day. Whenever I did nurse him he would fall asleep, so I just didn't feel that confident since he needed his calories. Once we got home I started to nurse more, but he just fell asleep a lot and there wasn't a lot of swallowing. The swallowing I did hear was gulping. His latch was also pretty shallow and painful. My nipples also were lipstick shaped when he came off. It seems like I would nurse for an hour, and then he would fall asleep, and wake up starving 15 minutes later. I know it isn't a supply issue, I pump around 65-70 ounces a day. Its like he can't transfer the milk very well. I feel like what he is getting from the breast is what I let down and it can just drip into his mouth. I have also noticed when he has a bottle he has trouble keeping suction on the bottle, milk sometimes shoots out the sides of his mouth, and I hear clicking noises. I saw a LC and she said it was nipple preference for the bottle and he was being lazy. But I am beginning to wonder if it is something else. Maybe a PTT? He loves being at the breast, and will latch (shallow) comfort nurse all day. I am really at a loss, he needs my milk, I have a ton to give, but what is going on?
