I wasn't going to come back on here, as it's all got way too heated and people are saying really nasty things on both sides. To set my case out I have bf both my sons for over a year, partly because of all the benefits I thought it would bring, partly because I was damn lucky that it all went very smoothly for me, and partly because I am bloody lazy. But I find all the boobygang monikers tedious, comments about how extended bf's do it for themselves are insulting etc.
I also find it insulting to insinuate that anyone who has not bf doesn't care as much or isn't as good a parent. Obviously that is utter shite. I have a lot of friends who tried and failed (or actually, decided they didn't want to do it), and you know what, that's fine so long as it was their decision and they didn't feel pressurised or didn't get support. I hate that one of my best friends still feels guilty for "only" having bf her son for 6 weeks.
Why the hell should it bother anyone else if it doesn't directly affect their life? It pisses me off just as much that my mum thinks it's appalling I bf my DS2 until he was nearly 2 just as much as it pisses me off that anyone should feel guilty etc about not bf.
But coming back to the intelligence thing - actually yes the most recent studies show that there is a (minor) difference to IQ if a child is bf. Well great, but is having a higher IQ actually always a better thing? I studied to a v high level at university and met some people with very high IQs who actually I have no desire for my children to be like. Yes sure I'd like them to be bright enough to do whatever they want to do. But I don't really think the additional 4 points of IQ or whatever it is is actually going to make a blind bit of difference to that, and actually if you gave me the choice of 4 points higher IQ or better socially adjusted, I know which one I'd go for every time, as I think it's the latter that will make you more successful in life.
Anyway that's all I'm saying, and really hope that hasn't offended anyone in anyway as I think there's already plenty enough of that going on.
