Saying "To make" to refer to going to the bathroom?

[rgG]

The only time I've heard anything similar to this would be when my Sister would ask her toddlers something along the lines of:
"Did you make poopoo?"
"Did you make peepee?"
"Did you make poopoo or peepee?"

I have never heard of adults using such wording when referring to themselves having to use a bathroom.

This is how I have heard it used.
