I am so worried that my 10 month old isn't getting enough milk. She has been bf since birth and usually feeds for about 5 minutes. But in the last week or so, she is only on for 2-3 minutes! She comes off and starts messing with my nipple!(pinching it!) If I try to put her back on, she either starts scraping my nipple with her top teeth or just bites me! She has 3 meals a day and is bf 3 times a day.
