It's interesting to hear the different perspectives. I know signing is encouraged however maybe it is just coincidence, but every child that I know that did signing with their parent spoke less often and later then other children. It may just be in the way it is presented by the parent. Perhaps the parents take the sign as the child's answer and don't follow up with the word like you Michelle. Who knows. I didn't sign with either of my children and they were both early talkers. Their grunts were always followed up by me with "use your words" and then I would say the word and they would try to repeat it to get what they want. You would be amazed what my 14 mos old can tell me verbally.
