My daughter is 10 now, but your comment triggered a memory I had buried so deep it was all but forgotten.

The rule was that we put the child on its back, undo her diaper and fold the front down, blow on her exposed nethers and then close the diaper again and wait. She immediately pees, every fucking time, I change her, she stays dry for longer, I get some fucking sleep.

I just reminded my wife of this ritual. We laughed. Take this forgotten knowledge from survivors of the bad times, whoever might read this.
