Hi, I'm thinking of taking advantage of the proximity of a sign language teacher and having her teach me and possibly my baby to sign. I'd heard that they can learn simple sign at six months, well before they start to speak. He thinks humans may have first commicated by sign and that verbal communication came as a result of a need to do other things with our hands. In any case I really, really doubt that teaching your baby sign could hurt in any way. This is to the mom who asked about signing and her 6-month old and whether it would inhibit his verbal language development.
Infants begin to use nonverbal gestures on their own.
The authors encourage parents to become intuned with these gestrues and to encourage them to foster communciation before children have verbal communication. I think it's a great idea to expose your son. Have fun and good luck. May even enhance it. Your baby is exposed to language all day from everyone and presumably you are speaking to her while your signing as well.
