It costs a lot of money to raise a child, but every once in a blue moon a little one may actually save you some cash.

Reddit user looseONtheGoose posted this photo of a receipt he and his wife received while dining out on Mother's Day with their 1-year-old daughter. This girl wasn't your typical screaming-and tossing-food-all-over-the-floor toddler that you always seem to hear about, though.

Nope, she was a little angel and the restaurant decided to reward the parents by knocking a few bucks off the bill.

Now there's a promotion just about any parent can get behind.
