Developmental milestones are used as a guide to know what children typically do at certain ages. Every child is different, however, and may meet these milestones earlier or later than indicated. However, you should be concerned if:

• Your baby does not startle or respond to sounds.
• By 3 months, your baby does not turn toward the source of sound or your voice.
• By 8 months, your baby does not babble, imitate speech sounds or use his voice to gain your attention.
• By 8 to 12 months, your baby does not respond when people talk to him or show interest in attempting to communicate.

If you have any concerns about your baby's hearing or speech/language, discuss them with your pediatrician. Early identification of hearing, speech or language problems is critical. Identifying potential problems early not only can assist with speech and language development, but also can prevent difficulties in the future with behavior, social interactions and academics.
