WASHINGTON (AP) -- Researchers say parents should do more than just talk to their toddlers -- they should gesture, too.
Studies find that pointing, waving bye-bye and other moves seem to boost a budding vocabulary.
Scientists found that tots who could convey more meaning with gestures at age 14 months went on to have a richer vocabulary as they prepared to start kindergarten.
The University of Chicago researchers also say they found a difference between families who were poor or middle class, with the higher-income parents gesturing more.
The study is reported in the journal Science.
