MrsBates, you say (apropos research into the health impact of infant feeding) : "But I think it is overstated and therefore often misleading. "
Where is is over-stated? Clearly, someone claiming that breastfeeding is 'a cure all' is deluded, and if they posted on a thread like this one, they'd be challenged. If you 'think' it is over-stated, then you will be challenged, too, to present examples of where this over-statement happens. I can think of one example here (when someone's doctor told her that her baby would not have eczema if she had breastfed which is clearly daft, 'cos how would he know?) but is this sort of thing happening often???
On a thread asking for help with a breastfeeding issue, with a mother facing a challenge like the baby not latching, or similar, I would not post (let alone 'bandy about' ) research into IQ and obesity.
But when threads like this one here move on to research (as they may do - the very title of the thread invites it) then why can't I (or anyone else) post relevant studies? I am at a genuine loss to know why we can't be grown up enough to talk in adult terms about it all - and yes, since you asked, I do think challenging this is childish. If discussion about the research upsets you at the moment, then I expect you, as an adult, to deal with it by hiding the thread.
