In parenting today, "teachable moment" is a buzz phrase. I had one a few minutes ago. Oldest Son picked up First Comes Love by Jennifer Davis and was reading though it. I quickly sat down to read it to him. Why? It is a book that helps explain about love and having babies. I bought it at Half Price Books when I was pregnant with Oldest Son. It is written in a rhyming scheme and discusses animals as well as people. It is beautifully illustrated. Highly recommend. But, make sure you read first because may be too explicit for some families.
