Wait I'm confused. Are you more worried about the fact that they fall asleep with a tv on or that they are in daycare until 6 pm and then sent to bed at 7? The latter is much more concerning to me. One hour to play, eat, do homework, do chores, and develop relationship within the family structure? That seems really insufficient. Granted I dont know what time they have to get up in the morning either.
My kids sometimes are put to sleep on the couch snuggled with me while I watch a show or two. They were sleeping about 8:30 pm to 7-8 am but my husbands schedule changed and now he gets home around 8:30 and there is no hope if getting them to sleep immediately because the desire to build relationship overrides the need for an "early bedtime" - now they often sleep more like 10 pm to 9 am.
I don't think falling asleep to the tv is the problem. I have been doing that for twenty years.
