Title: My two year old knows how to open the covers.
Review: These were childproof for a while until my son turned two. Now he can easily get them to open. Just recently, he opened one and then turned on the knob to our gas stove filling the kitchen with the smell of gas. Luckily, it wasn't on for long before I noticed and was able to open up all the windows to air out the smell of gas. So now I need to look for a different child proofing alternative. :(
