why my 9 month old not respond his name some times. (watching tv, playing with toys)

A. First, consider your baby's age. While some babies are able to recognize their names as early as 4 to 6 months, most should reach this point consistently by 7 to 9 months. Second, take note of consistency. Your little one should turn to look at you or vocalize (make noises) when you say their name.
