at a mother and baby group I attend with my 6mo DS, one of the helpers was saying that you should limit tv time to half an hour per day.
Now my DS loves the tv and watches it for more than half an hour per day! When Waybaloo comes on he stops dead and is glued!!
Im really not that concerned as its not on ALL day and and we do go out and interact with people and eachother everyday.
I knew I would have a tv addict from the start as when he was a week old I was changing his nappy on the living room floor and he was transfixed by corrie!! 
My mum says its sad that he enjoys the tv so much at his age....what are your views on children and tv???
