I'm not saying there isn't a small amount of women who are genuinely unable to bf or have a low supply, just many are told that incorrectly because we have woeful bf support services in some areas.
You may not be saying that but you'd be surprised by the number who do! Including post-natal midwives, who are very often the only breastfeeding support women have contact with. I saw two midwives and a health visitor before I was diagnosed by a lactation consultant.
I very much agree that support for women trying to breastfeed is lacking in most areas, and that it's harmful for women to think they can't full stop when in fact they could if they had that support. But it's also NOT helpful for those women who do have problems not to be able to get the more specialist help they might need or the understanding of what is wrong.
Some will say that a very small number of women really can't breastfeed but there's pretty much no information about who those women are, why they can't, and the ways they might find out if that's them. And actually the number of women who have problems is rising as it's often linked to insulin resistance or thyroid issues.
Sorry, this became something I lived through for years, going from being told by the local breast clinic that my breasts were perfectly normal (and in one way of course they are - it's a natural variation) all the way through to starving baby and a huge amount of emotional upset. The online support groups I am a member of are full of women who had similar experiences.
I think it's probably fitting for the proportions that this thread has mostly women who didn't experience growth but could breastfeed with no problems but a small number of posters that did have problems, because no growth in pregnancy occasionally is a genuine problem.
