Julian, I think that you've made some very good points and I tend to agree with you that linking benefits to some sort of parenting education is a good thing. My children are younger than yours (3 and nearly 5 years old) and I would say that, in addition to what we learnt from our own parents, we can pick up new knowledge from grandparents (who have often 'improved' the second time around), from discussions with other parents at playgroups or schools, teachers and the television. Thank heavens for Supernanny.
