Choices and some sense of control

I wonder if anyone was given a choice in what location their rectal temperature would be taken? When my 2 boys were young, unless they were already sick in bed, I would always give them a choice. I would say, “where do you want to lie down so that I can take your temperature”. That accomplished 2 things. First by telling them they would be lying down they knew it would be taken rectally. Seond, by giving them the choice ( sometimes the sofa, sometimes their bed, sometimes my bed) they had some sense of control over what was about to be happening. That seemed to help as I never had any resistance from them about baring their butts for a RT. By about age 8/9 they had been switched to oral unless there was a special need for RT. Any thoughts or personal experiences with that?
