How do you get your bub to show their face for ultrasound?

Meri

At recent ultrasounds (weeks 16 & 20), baby girl has decided to burrow her face down near my butt for a sleep, and although we got a good shot to know her birth gender early, it'd be nice to see her face😂 (face on or profile).

What have you done to get your baby to move around/wake up for ultrasounds?
