Sleep I need... I'm starting to. The baby will sleep for 8 hours at a stretch- I do the evil co-sleeping thing, so he nurses at will and does not even wake me any more. But 3 days a week, he'll be up and only sleep that 8 or 9 hour block... I went into an office to work for two weeks during the day over Xmas and that nearly killed me 'cause 2-6 AM is my Little Lord and Master's favorite party time.
I'm so happy overall- I know the lack of sleep isn't good, but I'm dealing with it pretty well.
It's getting better.
