His time of the month

I am a mother of two boys. By definition I deal with weird, gross stains on every textile that enters my home. Suspicious brown smears on clothes (just wash them, don't smell), sticky green goo on my own shirt (small people like to use me as a Kleenex), a combination of blood and snot used to finger paint on a bed sheet...I've seen and usually identified it all. Or so I thought until I was doing laundry this morning.  I first gagged and then stared quizzically at this head scratcher of a stain. I carefully examined it and believe I have figured it out.  It's a period stain. Yep. My two year old son must have started his period.
