I understand that it comes from the Gill Rapley book, which I haven't read so forgive me my question, but where does she get it from?
I'm just interested as it appears to be so different from the advice that we are given here in Australia, which is to crack on with food, and that babies should be pretty much having 3 meals a day of normal food by the time they are a year old.
I'm not questionning BLW as I think it seems like a great idea, but I just wondered what studies support the mantra really.
