Those of us with young kids, like myself, know that toddlers can get into trouble anywhere they go. They also have absolutely no concept of fear, or concern for their safety—which leaves us parents watching every move they make and executing many last-minute “saves.” So, when we find a product or a service that helps make our kids a little safer—and gives us one less thing to worry about—it’s pretty much a no-brainer, right?

There’s now a feature like this for replacement windows, called “Window Operating Control Devices” or WOCDs. Have you ever feared that your child may accidentally fall from a second- or third-story window in your home? Been amazed (and terrified!) by how easily your little one could open your windows? That’s what WOCDs help protect against—these tragic accidental falls.

Basically, a WOCD is a ventilation limit latch that is “always on,” which makes it less likely that a child could open a window on his or her own and accidentally fall out. They’re a bright red color and they always stick out—allowing the window to open only a few inches. They must actually be operated to open the sash more than four inches—unlike standard vent latches, which can be toggled on or off. Overall, WOCDs are pretty effective, and they’re a lot prettier than installing bars on your windows to keep your kids in!

So if you’re a parent of a young child, WOCDs might be something to consider for your home—just one more little way you can gain some extra peace of mind (and maybe a whole minute to yourself!).
