Ok ladies here comes me with more information......(all info I give is from the lengthy convos with my LLL leader and reading recommend books by the LLL)
First things first. Since the both of you have babies that is fussing only on the one side then I would wonder if he may need some body work. So going to see an osteopath or chiropractor. Especially if you had a bit of troubles getting him out, like pulling on them or foreceps. (D was pulled on hard and was off on the left side all the down from head to pelvis) also try side by side laying down position way better than football.
Secondly fast flow is best helped with the laid back position, nursing on one side continually until baby is satisfied. Also laying down side by side resting baby's head on your arm so his head above the flow, can be good for fast flow. D likes laying down with me for my left side especially. I think I was controlling the breast too much and made him even more mad, so letting him have more control has helped my nips heal faster.
Thirdly P it does sound like thrush with the other symptoms you are talking about. Starting a probiotic sooner will help get rid of it faster once medications are administered. I have always started with the natrual products first. Like gentian violet, grapefruit seed oil, even APNO has a anti fungal in it and helps with sore nips.
Fourthly seek help with a LLL leader. The best thing I could have done. She will help you more than you can imagine and don't just call once. Go to meetings too if you can. You may find something another mom has done that may work for you too. It is awesome.
Now the books I got my info from are Breastfeeding Made Simple, and The Womanly Art of Breastfeeding (which is the one I'm reading now and LOvE it) It is really like a meeting in a book. I feel supported just reading it.
I hope all of this helps. You can ask me anything too and I will look it up if I don't already know the answer
