Anatomy scan

Hey guys, I have my anatomy ultrasound on Wednesday and the following day we have a gender reveal photo shoot. I'm kinda worried that the baby won't be active enough for us to get the gender. Everytime we've had an ultrasound the baby's been super active. Is there anything I could do before the ultrasound that would make the baby more active to assure I get the gender during the ultrasound ?? Thanks 😊
