For me it's just lazy or people apportion blame to those who can't defend themselves (ie, the kids need to be in bed by 6pm). No they don't, utter horsecack. Kids will sleep if kids need to sleep. We have friends who bring their newborn baby out with them everywhere, evening meals, pub drinks, everything, and their older boy comes too. Just asleep, or, awake for a bit, then he falls asleep. Went out to downtown Disney the other night, near on 10pm, and it was full of parents who realise, their lives will just come to a crashing end if they start to let their children rule their social lives. Most of the kids were asleep or still awake totally enjoying the experience.
