I could see this happening at my house.  Luckily, I've never had to call the authorities.

A couple in Wales, whose 5-year-old son went missing, said their daughter found him napping under a beanbag chair in the living room nearly an hour after officials began their search, which included police dogs and a helicopter.

I almost didn't make it to work this morning, because I couldn't find my 5 year old son.  As it turns out, he was curled up and sleeping on the floor next to my husband's bed.  This kid can fall asleep anywhere.  (see pics)

Something similar also happened several years ago with my middle child, Gracie.  I was in a panic, even though the door was locked and I knew she hadn't left.  I called my husband to come home.  She was asleep in my closet.

I realize, as I write this, I may sound like a bad parent, but it happens!

Anything like this ever happen to you?
