Every single ultrasound I had with Sophia the tech said two things: "wow, she's really moving, isn't she?" and "her hands are up by her face."
She would push on my belly, or buzz it with some weird fetus-hazing buzzer, to try to get her to move her hands. I remember her muttering during the last ultrasound, "Is there ANY WAY to get this girl to put her hands down?"
If I'd known then what I know now, I could have told her.
No, there is not.
She will have her hands up.
And she likes it that way.
