Fetus makes a move

I think, at 20 weeks, I'm finally feeling Fetus move. On Sunday, I told Hubby I thought Fetus was moving but, yet again, I wasn't sure (how can I be sure if I've never felt this before?). He put his hand on my belly and right as I said "there it is!", he said "I feel it!" It was so neat for us both to be sure Fetus moved at the same time, for the first time.

So, what does a baby moving feel like? I've heard people describe it as flutters, "like gas," and round circles by an eraser. For me, it felt like when you're really hungry and your stomach gurgles big bubbles. Only it wasn't an empty-feeling bubble, but a bubble with a bit of weight to it, and the bubble protruded rather than surrounding negative space. And it was a surprisingly natural feeling. You'd think it would be an extremely odd sensation, this being moving around inside you. But really it was an extension of internal movements I've felt before, only with a much more emotional personal reaction - obviously.

I have to wonder what effect all my mass transit riding will do to Fetus when s/he grows up. Is baby going to be a roller coaster junkie?

Fetus keeps becoming a more and more concrete thing in our lives, and I'm grateful for the gradual change. Imagine if babies were born hours after conception!

I still don't feel 100% sure I'm feeling Fetus move. I feel like I need to have her/him move more actively and strongly before I can be sure that what I felt before (now) is indeed fetal movement.
