They do fend for themselves. Problem is, I end up awake anyway because they are bickering! Lol. Or, they will come and ask me stupid things while I'm still in bed. Like I'm really going to "buy" them an app at 7 am when they know I want to be sleeping?? That's mainly my 5 year old, although the 7 year old is guilty of it, too. Maybe I just need a bigger house so I can be further removed from the noise
