Towards the end of feedings, my 4-week-old son almost always gets fussy. He will search frantically for my breast, latch on aggressively - take a few sucks, and then pull off violently and crying. I have tried burping him during this time, giving him a pacifier (I have an oversupply, so in case he wants to suck but doesn't want milk), holding him in various positions, and more. I'm not sure how to handle this when it's happening. Should I let him keep latching and pulling off? Or should I assume he's done feeding and remove my breast from the equation and try soothing him another way? After an hour of this love-hate relationship my nipples become extremely sore. He latches correctly most of the time, but he is so strong that the initial first sucks are very hard on my nipples.
Any suggestions would be greatly appreciated!
