We must know different locals Ummjake as most I know (lots, obviously!) have their kids in bed at a reasonable time. I think schools should continue to operate in Ramadan. Our schedule doesn't really change much during this month. Staying up late and eating into the night rather negates to point of fasting IMHO. We actually sleep less (gget up earlier for suhoor) and eat less (can't eat much if you've fasted all day) in Ramadan and carry on as normal during the day as much as we can and set aside more time for spiritual endeavours. At weekends we shake loose a bit more and join family and friends for get togethers but in the week it's business as usual.
