Talk to your child's doctor if your child hasn't mastered most of the speech and language development milestones for his or her age or you're concerned about any aspect of your child's development. Speech delays occur for many reasons, including hearing loss. Depending on the circumstances, your child's doctor might refer your child to a hearing specialist (audiologist) or a speech and language specialist.
In the meantime, encourage your child's speech and language development. Read to your child. Talk to your child. Sing songs together. Teach your child signs or gestures for common items or phrases. Ask your child questions, and acknowledge your child's responses — even if he or she is hard to understand.
