I'm not getting sleep - she's still waking up! But in 6 months or so I'm going to be in lots of pain.
My ovaries don't work properly so I'm not sure I want to fiddle around with hormonal contraceptives.... but maybe I'll look into it.

It's the consistent 8+ hour gap that does it for me

There are some women who just don't get cycles till they've weaned completely. Or so I've heard.
