Review on 🚪 6-Pack Baby Safety Sliding Glass Door Locks - Childproof Slide Windows & Closet Doors - Ideal for Sliding Patio Door Locking (White) by Jane Cuperus

My son likes to climb and tries to stay on the windowsill. I was always worried that one day he would learn how to open the sliding window, press the screen and fall out. We won't do it again! These small devices prevent the window from opening further than it is safe to do. I did this by resting its head against the hole and making sure it couldn't get through. So I can leave the window open even on hot days and not worry so much about the spirit of adventure. They're also great for keeping him from opening our patio door when he shouldn't. And if you want to open the outside of the unit, they fold easily and lay flat against the window for easy opening. When opened they even look cute on the glass and remind me of bumblebees.
