how long have you been breastfeeding? if you’re just starting out, your baby might outgrow it within a few weeks. my son did the same exact thing for the first few weeks but outgrew it by about 4 weeks. a few things that my lactation consultant suggested that worked were:
– like the PP said, each time your baby latches incorrectly, break the latch with your finger at the side of her mouth. it teaches her not to latch poorly and also saves your nipples from some excruciating pain. when you relatch, it’s important to catch that exact moment when she opens their mouth super wide and POP your nipple in as deep as you can. it can get tedious, but it will work out eventually with practice.
– switch positions and breasts at each feeding. the hospital lactation consultant (and many breastfeeding books) often recommend to do 10-15 mins on one side, and then switch. but this can lead to your baby getting to much foremilk and not enough hindmilk (which my baby started showing signs of…) AND increases the number of times per feeding that you have to accomplish a good latch. so i just do one breast per feeding. in addition, changing holds (football hold one time, cradle hold the next, etc.) will put pressure on different parts of your nipple each time and save you from some pain.
– not sure if this is one of the exercises your consultant recommended, but practice helping your baby suck with their tongue down by letting them suck on your (clean) finger and gently pushing their tongue down with each suck. i didn’t do this that much, but i do think it helped a bit.
– catch the baby before they are starving and frantic. in those early weeks, when DS was hungry, he was HUNGRY FAST. i had to really catch him before he was crying frantically or else he would get super frustrated when trying to latch on, making it really hard for him to get a good latch. i would suggest that if your baby seems hungry at all, offer a feeding first and if they are still fussy, eliminate other things (diaper change, over/under stimulation, etc).
also, if it’s any comfort, my nipples were a hot mess for the first few weeks. i couldn’t believe that women have been doing this for centuries. it was excruciating – cracking, scabbing, raw areas. UGH. but it did heal and now bfing is painless and actually very gratifying. hang in there 🙂
