you see, in the beginning your breasts will feel like they are going to burst! especially, in the days after the milk comes in (I could not believe how big mine crew and it hurt

). as well with those big engorged ones it hurts when the baby latches on! but as your milk poduction establishes they go back in size and go all soft again, that it is really hard to believe that the baby can feed so much out of it. then it is not painful anymore when the baby latches on!
give it another week and you should see an improvement, I reckon
