Help!

Brittney
Since my LO was born I've been exclusively breastfeeding but recently she has begun fighting at the breast. She latches fine then comes off and writhes from side to side and gets fussy. Once she latches for a good amount of time she wiggles and grunts/groans, sometimes cries, and pulls my nipple. I'm not sure why this is happening and it doesn't matter what time of day or what hold I use, the result is the same. I also notice that when I pump I'm only producing about an ounce total from both breasts. I usually pump right after breastfeeding LO. Has anyone else been dealing with either of these issues and maybe has a solution? I could really use some advice. Thank you!
