I loved this book. It is packed not only with beautiful, inspiring images, but also great information. It would be a fantastic read for beginners, or parents wanting to take better pictures of their kids, yet it is also full of very useful and honest information that a professional would appreciate. I agree with another reviewer that more technical information would have been very helpful, but that's it's only fault.
I thoroughly recommend this book - I actually got it from the library (sorry Amazon!) but I will probably buy it as I'll want to keep refering to it in the future. It's how a book on children's portrait photography should be like. Buy it.
