Turn waiting for an appointment into a Sound Off. Make different sounds like a whisper, peep, ding, or roar. Pause after each sound so your child can respond. Does he/she smile? Look at you? Make a sound himself/herself? Try a new sound. Keep going back and forth!
This back and forth conversation with sounds gives your child practice listening and helps him/her learn to notice differences in sounds, the foundation for language development and communicating with others.
