My sister is about a week less pregnant than I am, but I swear, her tummy - just her tummy - is more than twice as big as mine. I would swear she were having twins if we didn't know that she isn't. She also has had much more extreme pregnancy symptoms than I have. Again, that's a sign of twins.

I'd love it if someone in our family would have twins. As long as it isn't me. In the meantime, I am fascinated by how different pregnancies progress totally differently, all pretty much ending the same way.

I've also been interested to note that this time, with baby #4, I go long periods of the day forgetting that I am pregnant at all. With baby #1, it was always on my mind. Always. It was really all I could think about. Same with baby #2, but I had some serious complications with that one that kept me anxious. WIth baby #3, I had REALLY bad morning sickness until about the 5th month, so that made me painfully aware that I was pregnant, 24/7.

This time, I've had some mild nausea, which seems to mostly have passed. I'm not sleepy all the time like I was for the first 8 weeks or so (though still a bit more tired than normal). And I am always busy, with my job, with the other children, with the house... I am often just too busy to remember that I am pregnant. I remember, though, when I turn over in bed. That's when the little belly I have makes itself known, as the ligaments stretch and ache. Then I remember, "Oh yeah! I'm pregnant," and then go back to sleep.
