Twice. They were both totally my fault. I fell asleep reading with them. The first time, Odysseus(given to nephew) found himself a place on my desk in the CD tower. Ophi found a nice blanket to curl up in.

I also fell asleep while studying with Ophi once. I woke up with her face in my face. She flicked her tongue at my nose. It was so priceless. She had this, "Momma, wake up; you're gonna be late for school" look. ^_^
