DENVER -- A little Denver girl recovers from a terrifying tumble out a third-story window Thursday night.
It's a sad story that happens too often during the summer, when families leave windows open to cool off their homes.
2-year-old Yannitza DeLeon is in serious condition at Denver Health Medical Center.
She broke some bones in her shoulder—but is expected to fully recover.
A safety expert tells us there are some simple things you can do to protect your child.
"I saw the girl looking outside," says witness Maria Marquez.
That little girl then pushes a window screen at the Osito Ridge Apartments in the 5800 block of Hampden Avenue and falls about 30-feet onto a tree, then onto rocks.
"She was bleeding because she fell out the window," says Marquez.
"Here in Denver, there are about 18 window falls a year and all of them are preventable," says Louis Delaware of Colorado Childproofers.
He literally wrote the book on childproofing homes called: “How To Childproof Your Home.”
He says windows are something parents often overlook.
"The majority of homes I go into there is no protection on the windows to keep the child from falling out. A screen has one purpose to keep bugs out," he says.
And he claims the problem is easy to fix.
"This is a flip-over window stop," he shows us a window safety tool. "This I install so there is a three-and-a-half inch opening."
It, and a window wedge and mechanical window stop, all prevent windows from opening very wide.
He says the safest product is a window guard that features metal bars screwed into the window frame.
“This way the window can be fully opened without the child falling through," he says.
They are simple products that can prevent difficult situations.
But they’re not always top of mind to parents—and part of the problem may be awareness.
"They don't see these goods in retail stores to remind them, 'Oh. Here is what I need to buy,’" he says.
Delaware also recommends moving furniture away from windows.
