When you mention that you sign to your baby, some people might initially feel sorry for you. When you pry a little bit more, you may find out that it’s because they think that your baby is somehow disabled.
However, many parents are realizing the benefits to signing, none of which requires that a baby be deaf or cognitively delayed. If fact, the research around baby sign language has shown that hearing babies are benefited immensely by being taught to sign. The research shows that babies who sign have more advanced vocabularies and even higher IQ’s.
I just raise this point because you should be ready to face certain amount of objection when signing to your baby and some of it might be misdirected (at best) or at worst harmful.
