"Jimmy, again?" I said, not surprised.
Jimmy wet the bed again, he's 4 years old and I potty trained him already at 3. But Jimmy says he just gets scared of the dark. Of course, he's only 4!
"I'm sorry, mom," Jimmy sorrowed, "I really am."
"It's fine, honey. It's normal at your age sweet heart."
Jimmy puffed out his cheeks, and looked like he was about to cry. I pulled Jimmy into a hug. I'm sorry, Jimmy, I thought.

I repeated the routine, washing for 45 minutes and drying for 45 minutes.
This was the first time in a month that he wet the bed. It's fine, I forgive him for it.
He is still young.
This is all going to pass away once he gets older...
I hope.
