Sleep Issues

Sharon here.... I think I may be getting too much sleep. A little crazy when you have an infant but here's the deal:
When I was working, I went to sleep between 10-11pm and would wake between 6-7am. That's 7 to 8 hours of sleep. Of course since Michael's arrival, my sleep has varied but it was mainly night sleep- few day naps. I guess I adjust well to different amounts of sleep because during those early weeks, I was probably getting 5-6 hours of sleep a night.
Fast forward to today..... Michael eats between 10-11pm and we both go to sleep. He wakes between 5-6am to feed again. And then we both go back to sleep until 8:30ish. I'm getting 9 hours of sleep a night.
That's not right!
