Our youngest son is just now beginning to communicate vocally. His older sister is forming sentences and learning new words every day, but we are just as pleased with the occasional grunt or squeal we get out of him. On one level, we are excited because this means that he is developing normally—something we never want to take for granted. But on an entirely different level, it also means that each day we are closer to hearing him describe his world in a way that we can understand. He is slowly learning to use his words.
