God, this is depressing.
Some of the posts here are depressing too - especially from people who have introduced solids at 6 mths or later and now think they have done harm :(
No one will ever come up with the right answers for every nutritional issue. All that can be done, if we are looking for public health guidance, is to use the research available at the time, chuck out the stuff that is poorly done, and assess the rest. That's what WHO did with the statement in 2001 which was reiterated in 2009,when the systematic review which led to '6 mths excl bf' came up for reassessment.
The paper in question here suggests another look at the research including studies which WHO did not look at. Perhaps these studies were not good quality, perhaps they looked at issues WHO were not concerned with, perhaps they came out later.
It's not a systematic review (a very specific, long-lasting, labour intensive academic process). It's not new research. It's a fairly cautious, fairly restrained discussion document which calls for further thought and in particular, further thought about the UK public health guidance.
The study itself is not funded by industry, according to what I heard on the radio.
University College Hospital's press office has gone bananas over this, because they know anything to do with infant feeding, especially something that can be spun to challenge 'orthodoxy', can bring them column inches. 99.99 per cent of academic papers never get one word anywhere near the press or mainstream media - but something like this is guarenteed huge coverage.
Nothing needs to change. Even within the UK guidance (published 2003) and the WHO statement (2001), allowance has been made for babies to be responded to individually - with the caveat that solids before 17 weeks has been shown to have a number of risks, in all settings. Which is why it was strange to hear Clare Byam Cook on TV talking about 3 mths or 12 pounds as a weaning point - not correct and not safe.
The worst behaviour has been the media, and I think the worst headline has to be the Independent's 'too much breastfeeding 'puts children off greens' '.
