Millions of toys are out there, and hundreds of new ones hit the stores each year. Toys are supposed to be fun and are an important part of any child's development. But each year, scores of kids are treated in hospital emergency departments for toy-related injuries. Choking is a particular risk for kids ages 3 or younger, because they tend to put objects in their mouths.

Manufacturers follow certain guidelines and label most new toys for specific age groups. But perhaps the most important thing a parent can do is to supervise play.

The U.S. Consumer Product Safety Commission (CPSC) closely monitors and regulates toys. Any toys made in — or imported into — the United States after 1995 must comply with CPSC standards.

Here are some general guidelines to keep in mind when shopping for toys:

Toys made of fabric should be labeled as flame resistant or flame retardant.

Stuffed toys should be washable.

Painted toys should be covered with lead-free paint.

Art materials should say nontoxic.

Crayons and paints should say ASTM D-4236 on the package, which means that they've been evaluated by the American Society for Testing and Materials.

Steer clear of older toys, even hand-me-downs from friends and family. Those toys might have sentimental value and are certainly cost-effective, but they may not meet current safety standards and may be so worn from play that they can break and become hazardous.

And make sure a toy isn't too loud for your child. The noise of some rattles, squeak toys, and musical or electronic toys can be as loud as a car horn — even louder if a child holds it directly to the ears — and can contribute to hearing damage.
