I had that when I was a baby. My parents brought me to the kiddy pool in the park. Well little did my folks know, but the water was pumped in from the canal where all the boats dock... I got it on my butt. I wasn't allowed to wear a diaper. Of course my folks had to take nudes of me lol Mom is laying in the grass & I'm in one of those round tobogins incase I pottied.. it was easier to clean up in that hehe

My dad still reminds me about it... I remember when you had to be a naked baby cause you got that nasty butt rash Dads
