GGgowiththeflow I don't think so, not on the whole.
There is very much an attitude, not from everybody but from some, that it is okay to bottlefeed if you can't breastfeed and that therefore choosing to do it is somehow less acceptable.
Just by making that distinction yourself in your post you have reinforced it a bit.
And many mums who genuinely can't breastfeed do feel guilty, perhaps much more so than the ones who can but choose not to. I've seen lots of posts on forums from people who feel that they have let themselves and their babies down because they genuinely cannot breastfeed when they wanted too.
I tried to breastfeed my son but it didn't work out. I was bleeding badly and he was starving. They were about to hospitalise us both when we made the very right decision to formula feed from then on.
But I have had a small number of people tell me that I just didn't try hard enough and that only 1% of people can't breastfeed so the rest of us who say we couldn't are wrong. Sod them, they weren't there, they didn't see the struggle we had or the very detrimental effect my determination to breastfeed had on me and my son.
And as I said, my friend was accused by a doctor of making her child ill because she didn't breastfeed. Turned out her child had cystic fibrosis, undiagnosed for many months, partly because the doctor had his judgy pants on and wouldn't consider any alternative reasons for her ill health.
Some people may be oversensitive and mistake positive reasons for breastfeeding to be criticism but not all. I think most have had a run in with at least one over zealous person who was out to make someone feel bad though, either way. Look on any forum and you will see posts by people who FF saying they have had a run in with someone who has judged them and made them feel bad. You will also see the same from people who BF saying they've had the same, mainly while feeding in public or from unsupportive family.
But either way, it doesn't matter. Nobody should be made to feel bad for their choice of feeding method, BF or FF. It really doesn't matter if it's just a handful of people who are really trying to make someone feel bad or if it is hoards of them as the OP feels Jo Frost was implying.
One person doing it is one too many and so, again, I feel Jo Frost was right to say that nobody should be made to feel bad because of the method they use to feed their own child.
