Anything given in moderation will be fine, even if it means exposing to a toddler to TV for half an hour a day. It is not possible to prevent Kyle from watching TV daily, as he spends most of his time in the weekdays at my mom's place.
I suppose this is a common dilemma that most working mothers experience when their child is left to another care-giver in the day. For any caregiver, it is easy to leave a kid in front of the TV every once in a while to give yourself a breather.
There is nothing inherently wrong with a child watching TV, but it matters how much time is spent in front of the TV and the kind of programmes that the child watches. Just as long you limit TV watching time and choose your programmes for your child carefully.
Kiddy Programmes like Hi-5, Sesame Street, Barney (although the purple dinosaur sure is annoying), Mickey Mouse Clubhouse (Mickey is a classic) are entertaining and educational at the same time.
I am amazed by the attention that Kyle gives when Hi-5 is on TV. He usually signals that he wants to be seated on the coach, and nothing seems to be able to distract him for a full 15 minutes.
Nothing seems to unfaze him, not even when dad comes along and plants a kiss on his cheek!
