6 hours generally.
My kids are 4 and 8 years old.
Even if the kids are sleeping all night and the Husband, I get up.
I have a consistent waking time, no matter what time I go to bed. Just naturally will wake at a certain time.
I have no trouble falling asleep.
Nor waking or going back to sleep.
I don't have a problem with interrupted sleep either.
I don't eat when awake. I'm not a snacker.
I am also the type that can exist fine on meager sleep hours.
I wake anywhere between 4:00am-6:00am. I don't need an alarm clock.
Sometimes I go back to sleep. Sometimes not.
I get things done, when everyone else is sleeping. And it is QUIET.
The only time, it is quiet.
