Oh, there was also the time that I gated DD into the playroom with me, and fell asleep on the floor (I was 9 months pregnant and exhuasted all the time). I woke up covered in marker.
I'm another one that needs my sleep. So after a night of getting up 8 or 9 times between the needs of the two kiddos, and then having my daughter spring out of bed at 3am expecting breakfast, I've been known to snooze on the sofa while she plays beside me.
But the worst messes have happened when I was wide awake and doing other "mom" things like cooking or washing diapers. My daughter went through a phase where she needed to rub creams and ointments all over herself, and everything around her. Diaper cream, moisturizer....whatever. Within 3 minutes, she could cover a room with it. I can't even count the amount of times it happened. Kids can make messes at lightning speed.
I think the only reason we haven't had a disaster like the OP's, is that the shelves in the pantry are too high for them to reach, even with their stools.
Those photos are priceless!
