CHICAGO (AP) -- Baby gates that are supposed to protect young children aren't always as safe as parents think.
A new study says nearly 2,000 U.S. kids get emergency room treatment each year from injuries resulting from falling through or climbing on these gates.
Most injuries weren't serious. But the researchers say parents should know about precautions.
That includes using bolted gates, not pressure-mounted ones, at the top of the stairs.
The researchers at Nationwide Children's Hospital in Columbus, Ohio, examined data on kids up to age 6.
They found that the number of kids who were injured on gates more than tripled over 20 years.
