If any of my kids needed quiet to sleep.........well they wouldn't sleep lol my babies can sleep through any noise and I have never tippy toed and forced others, even in my own house, to subscribe to an impossible version of quiet. It just can't be done unless your alone. I think even in restless or light sleepers that's just compounding the problem.

I think my dh is a good case of sleep training working. He wasn't the deepest sleeper before he joined the military but after 12 years of learning to sleep through noise (from general noise to being rocketed) the man sleeps like the dead! Almost to the point of ridiculousness, the kids can be squealing right next to his head and he is still snoring away. One of our kids inherited that outright, one is a deep sleeper when he is asleep and one is a light sleeper but he has learnt to manage.

But I'd agree that people do pay off kids as not important for consideration in a lot of things sure. And that's not cool.
