In every new parent class I took leaving up to the birth of my daughter, no one EVER mentioned the importance of pulling the little frills out on the legs after changing a diaper.

I heroically volunteered to change her diaper during a hockey game, and when I got back to our seats I handed her off to my wife. About 5 minutes later my wife was covered in pee and asked why I hadn’t pulled out the frills.

That’s a mistake you don’t make more than once… and I try to warn all new parents so they can learn from my mistake.
