When BioMom's quiet, she'll feel Itsy moving around with fairly subtle movements. At those times, it is clearly awake and floating around, reaching out with its arms and legs.
But then she'll feel a huge kick or punch that will appear, to me, as though she (BioMom) has the hiccups or something.
And then I'll rush over to try to feel Itsy. . . . Nothing will happen. BioMom suspects Itsy to have had the Jimmy leg just as he/she was falling asleep!
