Ok, the original thread actually said that bf babies were more intelligent not because of bm but because their mum's were more intelligent...thread was killed by obsessive spamming from one idiot MNer and I would have been happy to let it die except that I clicked on a link on another thread and then came across this article which says that bf for even 4 weeks can have "?significant? effect on a child?s development in primary and secondary school".
Thought it might be an interesting way to reopen the debate given that many posters were saying there was lack of evidence for any intellectual benefits of bf.
