A parenting trial

 Here is a good trial which the BMJ short-changed by printing in its hard copy a ridiculously short summary. You need to read the full write-up online.

Little comment needed from me, except perhaps to point out that parenting trials, though important, measure us a proxy result - better parenting - rather than the thing we want - better (i.e. happier and healthier) children. On the other hand, as the authors point out, there is good evidence that poor bonding between mother and infant reliably predicts trouble later on.
