 So this is from one of our writers who is a trained psychologist and this is based on some research out of Canada, but risky play is defined as thrilling and exciting forms of free play that involve uncertainty of outcome and the possibility of injury. In other words, let your kids go outside and play make believe, climb trees, whatever. There might be a little risk of injury, but it's really, really good for them. And it's so much better than keeping them indoors and on screens and what maybe some parents actually think is safe.
