Another tool in the parental kit: those small adult gadgets with touch-screen technology, so easy a child, even a toddler, can use them.

Parents are discovering that iPhone and iPod Touch applications, or apps, are a handy distraction and an engaging, even educational, way to keep young children busy. (Other handheld devices are getting in the game now, too.)

"It's been a lifesaver a lot of times," said Anna Friend of Westwood, Kan.

Life serves up some downtime for her younger son, 6-year-old Brady — waiting at big brother's activities, at restaurants — and at such times he has enjoyed apps ranging from racing games to math practice.

"It's helped me keep my sanity and kept him busy," she said.

And many apps are cheap (not counting the cost of the device). Here are five worth checking out for toddlers and preschoolers.
