I am definitely sold on the merits of swaddling and baby wearing, so this seemed like a good book to have. I was hoping for something that would show me lots of different types of wraps/slings I could do myself, so I was disappointed that the book contained very few *different* techniques.
The book illustrates five ways to wrap a baby, but one of them (the arms-free wrap) is essentially the same as a different wrap (the fast wrap), only performed lower on the body. What's more, only one wrap (the snug wrap) swaddles the baby tightly enough to keep arms at the side and baby pacified for long enough to sleep -- and it's the same swaddle illustrated in Harvey Karp's "The Happiest Baby on the Block".
The same criticism applies to the slings for baby wearing. The book only covers three types of slings, and one of them (the back sling) is identical to another (the front sling), only done on the back instead of the front.
The rest of the book goes over wrap/sling variations, which are essentially suggestions for different types of fabric or wrapping material for different occasions. On the positive side, the pictures of babies all wrapped (or slinged) up are really adorable, and the author fills out the book with humorous advice. And, bottom line, it's cool to be able to perform a snug wrap or basic sling using only a receiving blanket or length of fabric, which is what this book can help you do. (Because of these positives, the book can still make a great baby shower gift.) I was just hoping the book would teach me more ways to wrap/sling my baby.
