First time ever in three pregnancies. So weird!!! I haven't felt a ton this time, I think because of placenta placement or something. So I never thought I'd notice something like that. I had my hand on my belly and realized my belly was going up and down in a different rhythm than my own breathing. It was a breathing rhythm, just not mine. Just plain wild!!!
I think it's hard to notice because you can't really FEEL it (or at least only very lightly at best) and you have to be really paying attention. I got baby doing it on video this morning and I'm pretty happy about it. Anyway, yay for others seeing it too
