It's raining, it's storming, the kids are going batty.
Go out. Head to Chuck E. Cheese (just don't forget your headache-busting pills). There are games suitable for children as young as 2. Entry is free. Most games require one token at 25 cents a turn. Go bowling, window-shopping at the mall or to an arcade such as Boomers.
Bond. Create a wacky story. One person starts a sentence, the next person finishes fills in a verb or adjective; the next person completes the sentence. Break out the board games, such as Apples to Apples.
Break the rules. Hand one of the kids a can of whipped cream and send him/her off to start a food fight in the bathroom or on the patio.
