Baby is very stubborn

I’ve been trying to get 3d pictures of my baby for a week now, and now I have to get rescheduled until next week to try again! I need help or tips to get him to move, I tried something sweet and cold or something that he likes to eat but he still won’t move. My mom said he is getting ready to sleep a lot since it’s getting close to my due date, and I really want these pic for my baby shower and his book but it seems like it’s not going to happen 😭😭
