We try to limit it. DS used to watch more, but I found it had a negative impact on his behaviour, so now it's a very infrequent thing - maybe 1 or 2 sessions per fortnight. Unless we're sick, then we have tv days. DD I want to keep away from the TV till she's 2.
This is us. The tv is not in our main area so you have to go to that room especially. There is just NEVER tv on a school day. So that really leaves weekends and we just end up doing other 'stuff'.

I really hate the negative behaviour that tv brings with it. Eg the sook that's it's been turned off etc.

My kids play so beautifully together most of the time and we have a pool and big backyard where they can ride and jump on a tramp. When we lived in a smaller backyard the tv was on more or when I have been very pregnant.

I might watch tv once a week. But in saying that I don't think it's been turned on for three weeks now. I watch some shows I like on the net, this suits my bed time.
