Monkey see? Monkey do. Kids mimic the adults around them. Hence the unfortunate playground incident when your 2-year-old let his pal have it with a string of four-letter words.

Set a better example: Put a pint-size home gym beside your own. The First Fitness collection by Aqua Leisure is sure to set any youngster on the right track. Products include a child-powered treadmill, elliptical-style air walker, jump rope with digital counter, and a do-it-yourself obstacle course.

Now that’s something to shoot off about.
