Doctors at St. Luke's Children's Hospital are seeing a startling number of children this year who were hurt from falling out of windows.

Since April, Saint Alphonsus and St. Luke's in Boise have treated nine children who've fallen out of windows.

One of those nine children is Aubrey Hansen. Aubrey's mother, Amber Boone, tells KTVB back on May 27th, she had just laid her three-year-old daughter down for a nap. Amber says she had gone downstairs to get ready for a Memorial Day camping trip when it happened.

"Next thing I knew my neighbor was banging on my door, and I started to get a little frustrated," Boone said. "'I was like who is banging on my door that hard,' but by the time I even got half way there, because I was in the kitchen, she stormed in and she said, 'I think your daughter fell, I think she fell.'"

Aubrey had fallen out of their two-story window and landed on the driveway.

"I saw her laying on top of the screen in the driveway," Boone said. "My first thing was like running to her and making sure she doesn't fall asleep, seeing if there's anything else, making sure she doesn't move."

Aubrey spent four days in the hospital with a fractured skull, a lacerated spleen, and her bowel was swollen shut. Today, she's back home, but is still recovering from the fall.

"Everything has healed other than the skull, that's going to take time. It's a bone. They said four to six months that it will heal," Boone said.

According to Dr. C. Katarina Biller with the St. Luke's Children's Hospital, it's something that happens more often than you would think.

"The Centers for Disease Control calls falls from heights actually the most preventable injury in children from birth to nine years of age," Dr. Biller said. "We see up to 15,000 incidents of this every year throughout the country."

There are safety measures you can take to ensure your child doesn't become a victim, including window locks and window screen bars. Dr. Biller also says you don't want to place any furniture a child could crawl on next to windows.

"Window safety is often overlooked and what we encourage parents to do is get on your hands and knees and look at your home as a child would or as a toddler would," Dr. Biller said.

Safety measures Amber Boone believes all parents with toddlers should have in place.

"Windows are dangerous, them and plugs should be the number one thing that is on all baby registries," Boone said.

The Garden City Police Department has ruled Aubrey's fall an accident.
