I have a lot of trouble breastfeeding our 6 week old son. He is our third kid, the first two I have breastfed till around 1 year of age, so I have a bit of experience with how things go, but with this one I am really at a loss what to do. Thing is, from the begining I could tell that he sucks weaker than his siblings were used to do, I know that he latches correctly, but he just does not seem to manage to extract the milk that well. First two weeks we tried to keep to breastfeeding exclusivelly, which did not go that well, as he did not gain any weight and hovered at the lowest point after the birth. Then we decided to start suplementing, and there I can see that the issue is his lack of effort to get the milk out - I noticed that I pumped lesser amount (I did try to pump to increase milk suply, even though now I think that was not an issue), also after breastfeeding he drinks the full amount of what he should from the bottle, as if he had nothing from the breast. It is rather frustrating, since breastfeeding now turned into more of a snack and nap, and real feeding goes through the bottle - and now he is gaining well. I thought well, ok, he will gain a bit, then maybe he will have more energy to feed from the boob - nope, he just seems to be not a big fan of sucking (he is uninterested in pacifier as well, when our first two kids were ready to suck on anything that ended up close to their mouth). Keeping him hungry does not work either, since he either cries his lungs out and spits the nipple in frustration that the milk is not dribling itself, or falls asleep after the tantrum and does not drink from the breast either... He does not have trush, actually it does not seem to be any logical reason why we have such a huge issue breastfeeding.
Any help/advice how to make lazy baby work harder? I would like to exclusivelly breastfeed, but pumping 6 times a day does not seem like a very enjoyable experience, besides that I have sensitive skin and from so much regular pumping with the pumps my breasts tend to get sore, so I have to do it by hand (which I am fairly good at after two first kids, but still). And I also still have to care for the older children, so the life can't just stop and evolve around breast milk for a year.
