DS is 3.3 years/ DD 8 months.
I think left to his own devices DS would watch telly all day.
I don't have TV on for me at all during the day but might watch something at lunchtime on iplayer whilst DD kips and DS watches telly but I wouldn't have it on as background noise. DS only watches SKy+'d stuff and we pick together what to record - so things like tikabilla/numberjacks but he also loves Wonder Pets at the moment
DD and DS spend two full days at nursery when I work so on nursery days, we get back around 5.30/45. Bath is at 6.30 so it's tv on til then. DS will though get up and turn it off when a programme I tell him is the last, finishes
On our days at home, we have a "no telly before lunch" rule, so none in the morning. He does two mornings at pre-school and will potter round with me after that whilst I get lunch/feed dd and put her down for nap. He'll then have about an hour/hour and half after we've had our lunch together (I then get a sit down to surf the net/make calls in peace/watch iplayer). Once DD gets up the TV goes off again. The concept of DS "playing quietly" in his room for that down time is absolutely alien in our house . He gave up his nap at lunchtime at 2.3years when I was pregnant so this is my sanity time still.
We are hardly ever in the house so out with friends, at the park etc etc and the tv can go on again after tea so about 5.30/40pm.
At weekends, the same rules apply.
If the weather is rubbish and in DD's early days I'd often cave in mid morning for a half hour or so but now she's bigger I don't.
DS is hilarious at weekends- if DH comes in and turns the TV on for some sporting event or something he says "Mummy says no TV before lunch" and he'll switch it off .
I don't agree with having it on in the background mainly because tbh I find the noise on top of kids noise/the washing machine and every friggin' appliance in my kitchen beeping at me for attention just a wee bit too much ! I did watch lots of telly as a child and as an adult love a good nnight in front of the box but have never been a fan of just "having it on " for the sake of it. I also love to read....no harm in it in doses in my opinion
