Bubbles!
Last night I was up doing my guitar lessons and my wife called me into the room. She is four and a half months pregnant and she was wondering if the baby moving around would feel like bubbles. I guessed that it probably would and put my hand on her stomach and wow! I could feel the baby hitting my hand every so often. That was a first for us and it was a very cool experience. I've been excited about my wife being pregnant but this made it seem much more real.
