Spencer has so many new tricks these days. He predictably responds to a request for a kiss, or asking him to clap his hands. He also claps for himself to celebrate accomplishments like getting a shape to fit through the correct slot in his jumbo shape sorter. He is very good at flipping off the light switch when we leave a room. (Turning on is trickier for him.) Jim has taught him how to safely dismount from the sofa or the bed, by turning onto his tummy and sliding his feet off until they hit the floor. (Then he sometimes claps for himself and falls because he can't stay standing up without holding on for supprt!)
Spencer now understands many words and their signs, including: light, stars, shoes, socks, bath, eat, drink and diaper. So far, the only signs he has voluntarily made back to us are light and bath. We've been using the book Baby Signs which my cousin Hedy gave as a gift when Spencer was born. We read that getting started can take months, so we keep trying.
