I voted 6, that's rough average/estimation... I'd say we average 6-7 hours most nights... sometimes less, sometimes more on the weekends. I go to bed around 10 and on a good night am woken twice during the night to feed her. She doesn't usually eat more than twice before we get out of bed at 7-7:30, but sometimes doesn't go back to sleep after eating. Last night, she ate and laid back down at 10:30. She woke up at 2:30 to eat and went back to sleep, but woke again an hour later just to be awake. We were up until a little after 5 when she finally nursed back to sleep, then she slept until 7:45. That was a good-ish night.
