Lots of interesting experience on here - I have RTFT and wanted to share my experience too.
I BFed DS until he was 9 months old - not exclusively, I pumped and my DH gave a dream feed with expressed milk every night (I pumped every night for up to an hour to make up one bottle and hated it) plus the occasional bottle of formula if we were out and about towards the end.
I hated every single second of breastfeeding. I never had a pain free feed in that entire time, the best I got to was "uncomfortable". DS was 9lbs 10ozs at birth and didn't lose any weight at all at the beginning so he was clearly feeding well. He was thriving. I wasn't. DS had a tongue tie that was diagnosed in week 1 and we got snipped privately after another few weeks but it didn't help much on pain front.
I went to a breastfeeding support group. I had 2 visits from a private lactation consultant. Everyone agreed that our latch was fine and I shouldn't still be in pain. I was.
I went to a cranial osteopath and DS had a course of treatment. Again, it made no real difference.
My HV was convinced that I had thrush. GP said (twice) that I didn't and they couldn't find anything physically wrong with me.
At this point I gave up asking for help and just got on with it. I dreaded each feed as I knew it would hurt. I resented DS. Feeds took up to an hour through the whole 9 months, they never really got any quicker. I avoided bfing out not because I had any negative comments but because I ended up stuck in one place for such a long time.
DS has just turned 2. It's only recently that I begin to feel properly bonded with him, squarely because of my Bfing experience.
Because DS was growing well (at 97%+ percentile), none of the HCPs I came across was that concerned about the situation or my well being. The fact that I was unhappy didnt seem to be a consideration. I wish someone had sat me down and said "you don't need to do this". Because BFing was taking up all my emotional and physical energy I couldn't think past it to what the other options might be.
It's very unlikely now we will have another DC. One of the main reasons is the horrible experience I had when DS was small - predominant driven by BFing - and the strain it put on my relationship with DH.
Sorry - this is so long but I felt like I needed to get it off my chest. I'm a strong advocate of BFing but I feel like there is a problem of balance. Successful BFing benefits the baby (I believe) and the mother. But unsuccessful breastfeeding benefits nobody. There needs to be more support both to improve the success rate and to act as a safety net if it doesn't work well.
