"there is no point in arguing that BF or FF is best for babies if you no longer give a shit what they eat once they're old enough to chew"
It's complete and utter bollocks to use this argument. Concern about how babies are fed tends to go hand in hand with a general interest in child health.
Most people who are strongly in favour of breastfeeding feel that way because they believe children have the right to be fed the most appropriate and safest diet possible - from birth onwards.
Posters on mumsnet on the other hand put lifestyle choices and the feelings of adults at the centre of this issue and have very little to say about the experience of children. It just doesn't really feature much as part of the discussion.
"you are suggesting that parents who ff will then go on to feed their children shit which I think is an unfair assumption"
No - I was suggesting that there is a strong association, not a causal relationship. Maybe I could have said it better.
"Obesity is not a class issue...it's a widespread problem right across the board."
I think it is a class issue.
"Obesity is linked to social class, being more common among those in the routine or semi-routine occupational groups than the managerial and professional groups. The link is stronger among women. In 2001, 30 per cent of women in routine occupations were classified as obese compared with 16 per cent in higher managerial and professional occupations. "
I suspect the fattest children in the UK are children from white working class backgrounds.
