Amazon Verified Purchase(What is this?)
This review is from: The Rough Guide to Travel with Babies & Young Children (Rough Guides Reference Titles) (Paperback)
I bought this book because I was going on a flight to America with my 11 month old.
Book seems reasonable but it didn't really tell me anything I don't know.
There is a section at the end with specific information about different countries which I suppose could be useful but I'm sure you could find that information by googling it.
