Introduction
Babies reach milestones at different times and sometimes in different orders. Some may develop earlier in some areas, but may be later in other areas. Every child develops at his/her own pace.
These milestones mark the progress of children's language development and acquisition in sign language as well as speech language.
Research shows that speech is "not critical to the human language acquisition process." It also shows that children using signed language as a first language progress through the same stages of language development as children using spoken language.
