Those baby gates - meant to protect little ones - may not be as safe as parents think. ABC News reports those baby gates parents put in doorways or at the tops of stairs are sending about two thousand kids every year to emergency rooms. This, from a study published in the journal Academic Pediatrics. The injuries happen when kids climb on - or fall through - the gates. Most injuries aren't serious. Researchers say it's important for parents to make sure the gates are bolted, not just held in place by pressure.
