This book is awesome! I ordered it off Amazon for dd and it is all about how babies are carried on their mother/father/grandmother/grandfather/sister's backs, etc with slings and such for each different region of the world. It also mentions nursing twice, this is one of my favorite kids books ever! The pictures are gorgeous and the back even has a section about each people group mentioned in the book. The only downside is that it is not a board book so I have to keep it out of dd's reach when we are not reading it.
