I have a six week old and now I can begin to relate. I used to have trouble waking up by 9am. Now I'm up for good at 6am. Friends had told me that in the first month they were getting about four hours of sleep a night. What they didn't tell me (and what I discovered the hard way) was that those four hours were really four discontiguous one-hour periods. Last night my child slept for 6 hours straight. Six hours! I got five hours contiguous out of that, and wow, I felt like a brand new person. I never thought I'd be estatic to get so little sleep.
