The point is those critics say that if you sign with a baby they won't learn to talk. But it's not going to stop them from talking. And there also are those who would say why stop a deaf child from talking if they have access to hearing?

It's interesting to see little children who are deaf, with deaf parents. Maybe the mommy is the only one who understands a certain sign the child does. The language development is similar no matter what the language is.
