A 3-year-old toddler is recovering at Children’s Hospital in Denver after falling from a second-story window at her Boulder home.

The girl, whose name hasn’t been released by police, was upstairs in her parents’ room about 5 p.m. Wednesday when she pushed on the screen of an open window and fell out of the Mapleton Street house, according to Boulder police.

The window, which was lower to the floor, was the only window in the house without safety devices, police said. Carolyn DiFalco, the toddler’s grandmother, said the window wasn’t strapped with safety devices because the family is doing home improvements in that room.

“She had taken so many precautions with the upper windows,” DiFalco said, listing gates, barriers and locks among the devices her daughter has installed to keep the couple’s three children younger than 5 safe.

When the toddler fell at least 12 feet, she landed on a deck in the back of the house.

“Of course, the parents are very distraught — they are very concerned,” DiFalco said.

But so far, the toddler doesn’t seem to have serious injuries.

“She’s talking, and everything’s normal,” DiFalco said. “She’s very lucky.”

Boulder police spokeswoman Sarah Huntley said the mother was downstairs when the toddler fell, and she kept the child immobile on the deck until paramedics arrived.

“She had her daughter’s head cradled in her hands,” Huntley said. “She responded appropriately.”

The couple is not facing any charges in the case, Huntley said.

“The family was very aware of windows and had taken great efforts to childproof their home,” she said. “But (toddlers) are very curious and adventurous, and they seem to have a radar for things that might be dangerous.”
