Whether parents will use speech, sign, or a combination with their child, they will need to provide their child with many opportunities to promote language and develop vocabulary skills.
Their child will use language to convey ideas, express feelings, meet their wants and needs, explain events, and interact with others.
Parents can help increase their child's language during play activities, daily routines, and child-care activities.
