I've bought a lot of parenting books in my time and some of them have actually been of some use.
But this is one of the few that combines tips from "ordinary" parents (mostly, but not all mothers) with some "expert" corroboration. Having been in many of the situations described in the book as a first time mum, I know the suggestions and advice it contains are pragmatic and have often worked for me.
The book is based on a successful and widely admired website which has a discussion forum for mums to exchange views on many issues including parenting. It is so wide-ranging and busy that sometimes really excellent advice gets "buried" even when it is a few weeks old. It was great to revisit some good tips on babycare that I had seen before but had forgotten about. And even in this day and age not everyone has internet access (especially at 3am when your baby is teething and commanding all your attention).
I'd really recommend this book in its own right (how many other "non-academic" parenting books have the guts to put in a bibliography of other similar publications?) and as an introduction to the website.
