This is an outstanding book. Not only a week-by-week development (more thorough and personal than other books), but a journal, nutritional guide, 3D/4D ultrasound picture book. The QR codes that link to your phone for videos is so awesome. This is truly a unique way to bond with baby like nothing I've seen before. It's so personal. A great way to cherish every pregnancy and keep memories. I recommend it for a gift for yourself or everyone you know who's expecting!
