Were you given "a chance" before the enema?

When you were a kid, did your mom give you a chance to try and make a bowel movement by yourself once she realized you were constipated or would she take measures immediately with an enema?

In my case I was given a chance to sit on the toilet/potty and try to do something even though nothing happend most of the times. I was so nervous and anxious that nothing would come out anyway. Tell me about your expierences.
