smiling, I am worried I have offended you, and you are perfectly right to defend what you said...but it's still not helpful, and you have implied I think/say things that I do not.
You say: "Formula can be a godsend to some breastfeeding mothers and it doesn't have to mean the end of breast feeding." I don't deny it and have not denied it here!
" I think the constant bashing of women from the moment they conceive until the time their child is weaned, with breast is best information is overkill that results in women feeling extremely guilty when they consider formula as an option and that absolutely shouldn't be the case." I am not a part of any bashing and I have written loads here about the pernicious effect of guilt.
Ok, you were more exploratory about expressing and teats - there are no teats which really are like a nipple though, despite what their marketing says :)
"Formula is balanced in that you don't need to worry about the fore and the hind, too much lactose, not enough fat." You don't need to worry about that with breastmilk, either - somehow or other, the research about fat in breastmilk has come to be something women stress about and there is no need for it.
"Knowing how much the baby has taken makes the mother feel better, I don't think I'm the only woman who sometimes wished there was a measure on her breast." I think you are right there - this is something mothers do worry about. But it does not help the situation - knowing how much does not mean the baby has had what he needs - he may need more, or less, at any feed!
I don't want to fall out with you, and I am certain you wanted to help and support. And it's not helping the OP to be discussing what you said, so I will shut up now!
