I am about to be told tomorrow by the pediatrician that for the 2nd time now, I cannot exclusively nurse a baby and have them gain weight. My DD had to be switched to formula after I was told she had lost way too much and needed supplementing and then she refused my breast after. Now with my DS, if he hasn't started gaining by tomorrow, which is already giving me 3 extra days past the "rule", I will be told the same. I'm very upset because I really thought it was working this time...my DS has milk running down his face when he comes off the breast or is removed because he's been snoozing and I cannot get him interested again, but he has had issues with sucking since he was born. He only properly sucks (giving me that tugging feeling and him visibly having a longer jaw movement) once in a while and the rest is nibbling at the breast and only sucking enough once in a while to swallow. I have been massaging my breast while he nurses but he still isn't getting enough. Has anyone overcome this and taught their newborn how to suck aggressively enough? Anyone have any insight why many, many women are able to breastfeed multiple children and I am about to fail at it with 2?
