I have been using a nipple shield since day 1 because of latch on problems (Medela contact silicone). My son had a tongue tie that was corrected, and my nipples are almost flat. They stick out a tiny bit like a half pea, and when pinched are about the size of a pea.
At 3 weeks, I felt he was old enough to try without it so I was more persistent when offering my nipple. He did latch on, not well I think, once he suckled for a little while, swallowed once or twice and then pushed off crying. Since then he has been getting more and more frustrated when I try to get him latched on my nipple.
Sadly my nipples did not get bigger with the use of a shield or with pumping.
Sometimes he does not even try to suck at all, sometimes he moves his lips over it in search for a real "nipple" and glides right over that tiny pea like nipple. If I am lucky he will suck a bit, but not strongly at all. I tried the breast sandwich, getting all of the areola in his mouth but nothing works.
Lactation consultants have not done more than shove the nipple in his face to the point where he is so frustrated he starts hating my breasts all together :(
I don't know what to do any more, I want to breastfeed long term and I am afraid a shield will mess with my milk supply.
