There are people who will start reading this book then about 100 pages into it realize that it's going nowhere fast. Take my advice and keep reading. It gets much better, and more interesting. The ending is really good, and might have even upped this review a star.ac

My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.

My almost 2yr old learned her numbers with this puzzle. It's wonderful and easy for little fingers. This is definately not a cheaply made puzzle.
