Studies have shown that learning sign language at an early age has a number of clear benefits for hearing children, including earlier and more advanced communication skill development and an accompanying reduction in irritation and aggravation. This entry in the WE SIGN collection features hours of fun, easy, and educational activity, allowing young kids and preschoolers to sign and sing along to classics like "Wheels on the Bus," "Stop, Look, and Listen," and "If You're Happy and You Know It."
