How old until baby is responsive to call? Like when you call him, he will turn his head? My brother said that our baby is not responding to calls as it should. I am not sure at what age will the baby be responsive. I know he can hear us because when my husband cough even when baby is sleeping, the baby will jump and cry because he heard the father coughing.

Should I get our baby to the paedriatic to check up on his visions, listening and smelling? Otherwise, what we can do at home that can test out to verify that everything is ok?
