If you put your children's dinner on the table and stick your head out the door for 23 seconds to talk to a neighbor, you may return to find your 16-month-old like this:
Yes, I realize I shouldn't have taken my eyes off of her.
No, I will never leave her alone for 23 seconds again.
Yes, I realize she's fast.
No, she wasn't starving.
Yes, I realize she could have fallen.
Yes, I learned my lesson. :-)
