Your baby's new obsession is walking. At 11 months most babies have a one–track mind. So don't be surprised if your baby insists on standing up and cruising around the furniture for hours at a time. Just when you think he's exhausted himself, and you, he's back up and at it again.

This month he's also beginning to comprehend some of the words directed at him, especially those accompanied by familiar intonations and facial expressions. In the next few months, you may be surprised to discover how much he understands. One day soon you will hear your baby making recognizable sounds, such as "buh" for bye or "da" for dad.
