Tips to get baby to move for ultrasound?

So I am paying a decent amount of money for my 4D ultrasound tomorrow, and if I'm unable to get good pictures they let you come back for free but id rather only have to go once!
Some back story on my little nugget, in EVERY ultrasound she's either 1) facing my back so we can't see her face 2) has her arms blocking her face or 3) both🙄 For this reason even at the anatomy scan I only got to see a glimpse of her profile. 
She moves a ton when I'm laying in bed at home, so I'm hoping it won't be an issue. What are some things I can to do to make sure she's active?
