I'm not convinced by this book. It contains a lot of sensible advice, but the writers - who I think are a separated couple - seem obsessive about the idea that any new partners of a parent must be kept away form children for at least two years. I find this bizarre - if a parent has a serious relationship with someone, the child will be aware of that, and wonder why they don't meet this person.
Other than that I found some useful advice in this book, but to be honest, other books I read were better
