We have "Sophie and the New Baby" and found it helpful in anticipating some of the issues that come up for older kids. Sophie has to wait a looooong time for the new baby, then when it comes it takes a lot of attention from her parents and isn't much fun. The book shows her expressing her anger and frustration and how her parents comfort her, and that after a while the baby becomes more fun.
Here's a link to it on amazon, there are also links from the page to other similar books... (even if I don't buy from amazon I like to go there and read reviews and comparisons!)
