My parents bought this for my husband and I two weeks ago when our little girl was born at 29 weeks. We have both found this book very helpful. My husband read is constantly while I was still hospitalized and I have been reading it since I came home. The NICU is an overwhelming place, and the nurses and doctors do their best to explain things in terms us non-medical people can understand. This book has thus far proven to be an excellent source we can reference on our own. It explains things in lay terms and the glossary in the back is excellent. If we don't understand something the nurse has told us, we just find it in this book and read on it. It has really helped to keep us calm and informed.I definately recommend this book. We will keep this book for as long as we need it and I'm sure it will continue to be helpful as our little blessing grows up.
