I could not agree more with some posts here about BFing being 'natural'. Yes, it's natural, but we're not 'naturalS' at it in technique! Milk is there, boobs are there, babies mouth is there...we've lost the in-between bits with the way our society operates. It operates behind closed doors where everything is a private matter and so much is not normalised to us.
When I mention that Oscar can feed for as long as he likes, some people say "what if you fall pregnant again?", and they are confused when I reiterate "for as long as he likes", because they are under the impression that feeding must cease when pregnant. That's an education issue.
With education (on more than just how to attach your baby, but on the many benefits of BM for mother and child) you have the comebacks to all sorts of criticisms. And when people realise that you know what you are doing and WHY, they stop saying dumb things (well, mostly).
