This has been a battle for a couple of days now. When I bf my 6 week old, she guzzles and drinks for about 30 minutes and my breasts feel less full. WHen she is ready to nurse again, she will suck for a couple of seconds and cry, she will suck again for a couple of seconds and then start crying again, this goes on for 20 minutes. So, I finally give her a bottle and she sucks it down. When it is time for her to nurse again my breasts feel more full and she nurses without crying but at the next feeding she will. Why is it at every other time I nurse her she guzzles but at the other feedings act like she isn't getting anything and takes the bottle. She does prefer to BF, thats for sure. I just don't understand what is going on here and its become frustrated. It doesn't help my left breast is killing me and everytime she lacthes I almost scream. My doctor can't find anything wrong and her latch looks fine.
