I felt mine for the first time last night! It was so weird. DH had his hand on my belly and was talking to the baby. Then he said "good night" and moved his hand away and I definitely felt a very distinct "flip/flutter." It was so unusual that I gasped out loud. (It was "big" enough that I instinctively looked down at my belly to see if the movement was visible.) So DH put his hand back and started talking to the baby again to see if it would move some more, and we waited and waited, and then DH said, "aw, I guess not. Good night again, then." and Bean flipped again! WHOA. DH couldn't feel it from the outside, of course, but it was pretty cool!
In three months I'm going to be begging this kid to hold still and stop using my ribcage as a punching bag. But for now... WOW!
