You are doing a brilliant job OP.
Just echoing the previous recommendations to get DC checked for tongue tie again - my DCs TT was missed by about 10 midwives despite being diagnosed by the first one, feeding being absilute agony and the lactation consultant we saw who eventually snipped it saying it was one of the worst ones she had ever seen!
I was even told by midwives that TT doesn't prevent feeding, that breastfeeding is supposed to hurt at the beginning and I should just get on with it. Thanks for the support ladies! BF didn't work out for us in the end, not for want of trying... I was devastated at the time and felt a failure for giving formula but DC is healthy, strong and happy and that's all that matters really.
Currently expecting DC2 and planning to try to feed the new baby but if it doesn't start working out within the first few weeks I will be remorselessly moving on to formula again.
I remember it seemed like BF was supposed to be the thing everyone did, everyone talked about it and how amazing it was for the bond with baby and how much better it was for baby and that formula fed babies have lower IQs etc and it was like a cult I wasn't allowed in because of my crap boobs and DCs poor tongue.
I felt awful at the time but it turns out that it didn't affect mine and DCs bond, in fact it probably made his bond with DH stronger earlier as he was able to do some of the feeding too.
At the moment I know it may seem like the be all and end all but in a year, no-one will ask you how you fed your baby.
Keep well - massive hug to you and I hope everything works out for you as you want it to, boobs or bottle.
