Montessori school thinks baby sign language increases IQ

Research shows that sign language taught to toddlers can improve later IQ scores by an average of 12 points. More than that, sign language allows infants to communicate before they are able to vocalize. Infants are able to communicate their needs and gain a feeling of control over their environment.

Early learning of languages is shown to enhance intellectual growth. It provides children with more flexibility in thinking, a better ear for listening and a larger vocabulary, while improving a child\’s understanding of his/her native language.  Further, languages open the door to other cultures.
