My ds is a very stroppy 2.4 and TV/DVD is one of the biggest points of contention in our house. I have set some rules, no TV before 8 in the morning then a baby einstien video (essential for a stess free nappy change) and we try to have a gap but not always, then Bob the builder for 20 minutes at 9 (if no playgroup) then off. He is waking up from his daytime nap screaming for a DVD and I've reached the end of my teather so have said no TV in the daytime until is time to cook tea then he has another hour or so until his dad gets home and then it's off. Does that sound reasonable?
