There's an interesting discussion on the merits or otherwise of the Channel 5's Attachment Parenting Programme over at Playing it by Ear. Liz, who was featured, has contributed to it.
My feeling: that the essential goodness of the British family did indeed shine through, despite heavy attempts by the editors to make them look peculiar. I also agree with Clare that there was some strange goings-on in the single child American family - the child will in all probability suffer terribly from the mother's narcissistic investment. The other American family struck me as potentially suffering from a similar problem, the mother appearing so extremely zealous that the children run the risk of seeing themselves as products of her ideas, and not individuals in their own right, but I may be wrong here. This could well have been another problem of the editing, with the editor prompting mum to proselytize about AP instead of relaxing and just getting on with it.
