Start baby proofing! These are the 17 worst hazards in the home for kids

“If you have a crib or a dresser up against a window, and a child can get onto that, they'll push that screen out,” says Marentette. “And that's the only thing between them and the ground below.” They could also reach window covering cords, which pose a serious risk for strangulation if they’re longer than 22 centimetres.

TIP: Health Canada recommends using cordless blinds, especially in kids’ rooms. Keep the windows themselves shut, locked and clear of furniture. If you need air circulation, don’t open the window more than an inch. You can also gate the window, but most importantly, Marentette says, “Be aware of it.”
