Random pregnancy musings

Why is it if I wake up after 4:00 to go to the bathroom, I cannot go back to sleep? If I wake up before then, and I almost always do, I don't have any problems. 4:00 is the magical time. I was up for almost 3 hours this morning and finally fell asleep for a quick 1 hour nap. Oh well, at least I got a short nap this afternoon. My last doctor's appointment, the doctor asked me how big Becca was when she was born. He said I've consistently measured big and said he didn't think I would ever have a small baby. That wasn't the most comforting thing, however, he is inducing me at 38 1/2 weeks so this should be a normal sized baby...hopefully.
