If you want your children to avoid sugar, Sarah says you shouldn't be bringing it into the house. Set the example by keeping your cabinets stocked with healthy snacks, and try your best to limit your kids' junk food intake to birthday parties.
There is, of course, a gray area. Sarah feels that a small amount of sweets a day is better for children than never at all; if they're forbidden, they'll want it even more. "Having a cookie or two with lunch is healthy. Having a whole package of cookies after school every day? Not so healthy," she says.
One approach she takes is to serve dessert with the meal, instead of after the meal. That way, your kids will lose the mentality of eating everything on their plate and then having more for dessert.
