Who gets more sleep at night: you or your SO?

I definitely sleep way more than Mrs. Bee at night. It's not even close. In my defense, I need more sleep than her. However even taking that into account, I sleep through the night whereas she has to wake up to pump and breastfeed.

I used to wake up early when Charlie was waking up around 4 or 5 am. But lately he's been sleeping in, and so I've been able to sleep a bit more. I actually wish he would wake up earlier, because I felt I was contributing more to the family when he was waking up earlier. But I know better than to complain about something so wonderful as a child sleeping in in the morning.

Who sleeps more at night: you or your partner?
