recently my lo hasn't been latching correctly. I've had issues getting her to open very wide from the beginning. she has a extremely strong suck, isnt tongue tied. Now she wont open hardly at all and when she does and i get a decent latch she pushes my nipple out to where she just has the nipple between her gums and its extremely painful. I've tried relatching her over and over and over again, changing positions and im so lost. I'm trying so hard to keep nursing her but im starting to get discouraged and it hurts so bad. its getting to the point i dread nursing. i live in a small town and resources are minimal. I've been thinking about trying nipple shields but not to sure on them. any advice?
