Secondary drowning: Did you know you could drown after you get out of the water?

A little boy drowned during his nap after he got out of the pool and walked to bed:

Johnny would have only had to inhale four ounces of water -- about six teaspoons -- to drown, and even less to injure his lung enough to become a victim of secondary drowning...

"If your child comes out of the pool and seems sleepy or lethargic, watch them very, very closely... Rush them to the hospital or call 9-1-1 immediately."

ADDED: There are actually 24 teaspoons in 4 fluid ounces.
