A few years ago, I knew a child who had several older siblings and did not seem to want to talk. It may have been that she wanted to get it just right before saying things or that she felt that she couldn't get a word in edgewise! Or it may have been simply that she was more comfortable communicating with her body and facial expressions than with her voice. She was in no way delayed but her reticence to communicate verbally brought much frustration to her and her family. So her mom started teaching her baby sign language, something she had never done with her older children. The change was amazing. Suddenly, the little one had a way to communicate that she could master until she was ready for words.
