'What to expect the first year' was THE most useful book we found when we had our first child, so we bought this follow up expecting the same valuable info.
I don't know whether it's a reflection on how weak this second book is (or whether we're just more confident now that we've gained some parental experience) but we've barely dipped into this book. When we HAVE wanted to find out something, the book hasn't provided the information we've been looking for and to be honest we just look up things on the web instead.
I also think that during the toddler years, each child is so unique that there isn't a 'one size fits all' instruction book... whereas for the first year all babies are pretty similar on the whole.
I wouldn't bother with this one.
