Exhaustion is putting raucous children to bed
Left to their own devices they'll  pain your head
Once you've finally settled them down
Your face will be stuck in a perma-frown
Later when you check if everything's OK
They'll look like angels sleeping away  
Don't be fooled by this little deception
Angelic sleeping children are the exception
Be ever aware, certain to stay on your toes
There may be nightmares, as everyone knows.....
