My baby (now 3 weeks) was never able to sucessfully latch on to my breast. We tried for sevral days before my nipples were cracked, bleeding and becoming infected. I was given a nipple shield by the hospital and have since purchased several others. When I use them they cause serious pain not just at the initial latch, but sometimes throughout the entire feeding session. It feels like a hard pinch. Also while she is having an adequate number of wet diapers every day she was not back at her birth by her two week appt and I am worried that we are doing something wrong. She takes the whole nipple in her mouth to the base, but then it gets distorted at the bottom, the plasic get kind of wrinked while she is sucking. Is that normal and do you guys have any tips for me because this pain is almost unbarable.
