Toddlers and tv...

How much tv do your 14 month olds 'watch'. My son watches about 30 mins most a day. He goes in his jumperoo with tv on whilst I make breakfast because if he doesn't he screams and then when he has finished breakfast the tv goes back on for about 15 mins whilst I tidy up. My husband is moaning at me, saying its too much. It's my way of coping and I don't think 30 mins is too much?! X
