4D Ultrasound Advice

So 28 weeks I went to have a 4D ultrasound and he stayed face down and we only got to see a part of his face twice so they let us come back today at 32 weeks for free but once again he was face down in my placenta and this time we didn't see anything but an ear. No matter how much she shook my stomach and pushed on it he would not turn over. So now I get to go back again in a week. Any suggestions on how to get him to be more active for it? I've tried orange juice and sugary donuts and he still just wasn't active.
