Q: My toddler is chubby - my guess is he's overweight by about 20 pounds. Is he old enough to be put on a diet? What kind of weight-loss diet is healthy for such a young child?

- Concerned Mom

A: Obviously, you should avoid giving your son sugary beverages and high-calorie snacks, such as cakes and cookies. But you should seek advice from your child's pediatrician to be sure that there are no underlying health issues causing the weight problem. Your doctor may also refer you to a nutritionist.

Also, make sure your toddler has plenty of time to run, jump, roll and play. Take him to the playground frequently.
