Yes, as children, we were usually tricked when it came to suppositories. We didn’t like them at all; if asked, we would have always said "no" and refused the medication.
For this reason, suppositories were typically administered without warning - slipped in quickly during everyday routines, such as changing a diaper, washing, drying off, getting dressed, or while we were distracted by a conversation, a game, or some other activity - or even while having our temperature taken rectally.
During these routine moments, we were completely relaxed. Our bottom muscles were loose, and - *whoosh*- the suppository would slide deep inside before we could even react. As a child, there was no way to resist, say "no," or discuss the matter. It simply happened, and once it was done, there was no way to prevent it from taking effect.
Back in my childhood, this method was quite common; using a distraction to quickly insert a suppository was a very popular trick. For my mother, it was extremely practical, convenient, simple, and very fast. That’s why she preferred using suppositories whenever we had a fever, pain, a cough, constipation, nausea, vomiting, teething issues, or gas, or even just to calm us down. It was the easiest way to administer medication. A brief moment of surprise and the suppository was already in. For all five of us children, this was often done without our consent or against our will, using this quick and simple approach. While it wasn’t exactly fair to us children, it was incredibly effective and easy for parents.
