Also when people baby proof windows in their homes they often forget those that aren’t often used such as windows in the bathroom. In order to reduce oversight it will be good to focus on one room at a time before you move to next one. Also it is important not to skip the room just because there are no windows as there are also other things in your home that you should baby proof.

Window Stops

Windows stops have a purpose to prevent a window from opening past a certain point. A good thing about this baby proof method is that it is visually discrete but on the other hand window will have very limited opening range.

That is why it is important to stick to rule not to allow more than 4 inches of opening because that suits the size of a 5 month old baby’s torso.

You should be very careful if you have vinyl windows and make sure to by a compatible window stop.

This can be good solution for single and double hung and sliders.

A good thing about this product is that you won’t need any special tools to install it and it is made of durable plastic.

It is also important to know that the window wedge is a child proofing product and can’t serve as a burglar prevention device.
In case you are planning to use window stop to hold the window open you have to be sure that window opening isn’t wider than four inches because a child won’t be able to fall out of a gap with this size.

Charley Bar

Charley Bar can be a good solution to baby proof sliding windows. Many parents don’t know for this method and it can be very effective.

It works like a boom gate. You will be able to open it freely when it is in the up position. The window is closed when the charley bar drops down to horizontal position.

The trick with this baby proofing method is to set it up upside down. In this way the bar will be placed high up and out of baby’s reach.  Most of these products can be cut with a hacksaw and be adapted to sliding windows of all sizes.

Window Guards

All the previous methods work well, but what to do in case you want to open a window and let a cool breeze in? This can be especially a problem in warmer months. A lot of parents just open a window to circulate the air to cool the house.

An opened window can be a fall hazard to a baby. How to cool your home and have a child safe at the same time? Window Guard can be a good solution. This product is consisted of a series of bars that are set apart at fixed widths. The gaps are designed to be smaller than four inches in order to prevent a baby from falling through.

People who live in urban areas such as New York, Boston or New Jersey can note that there are specific styles of window guards approved for use for building codes and home builder’s regulations. Maybe to some of you this can be trivial but when you think better, it really does matter.

On the first place, responders want to know they will be enabled to gain entry through the guards in an emergency such as house fire and get into children’s room from outside. That is why it is good to check if the guard has an emergency release and if it is approved to be used in bedroom because some of these guards aren’t.

This solution is good for sliders, awning, single and double hung and casement.

Shard-proof Window Films

This is a good solution when you need to baby proof and protect loose glass shards after window break. As you know, tempered glass can break into bazillion shards that can get anywhere and can be a great danger to your little one.

A transparent Window Films can be a good choice because they prevent the shards from getting everywhere. Always have on your mind that it doesn’t prevent a crack or break of the glass, it just contains the shards. One more, good thing about these products is that they are UV treated.

These products can be convenient for casement, sliders and non-opening windows.

Window Cord Retrofit Kits

These products can fit into the broader window safety bucket, but on the other hand they also can be a threat for your baby. In case you have window treatments that have cords hanging down, they can be very dangerous for your little one. Our recommendation is if you have this at home, you should replace it with a cordless window covering. If this is expensive for you, don’t worry. The Window Covering Safety Council has amazing online resources and offers free cord retrofit kits.

What to do with crank windows?

There is a simple trick how to keep casement or crank windows. If you look closely to crank that serves to open the window you will see that crank handle can be removed. All you will have to do is to unscrew it or just pull straight off.

We recommend you to be careful not to damage the crank handle so you don’t need to use too much force.

What to do with unusual windows?

In case you have some unusual window, don’t worry. There is a DIY solution that can be applied to almost any window.

You will need for this Velcro strip, measuring tape, glue and Lexan sheet. First you will need to measure the space across window frame and write it down. Then measure the vertical of your window and write it down. You should also pick a point that is high enough to keep your little one safe. Most of the parents stick with half the window height.

When you are done with measuring you will need to cut Lexan sheet using those measures. Velcro should be attached along the sides of the Lexan sheet and the hooks to the window frame using glue. You will get a sturdy child proof window cover that allows light through.

You can also do some optional things like drill holes in Lexan in order to allow airflow. You should also make sure to find out how to drill through plastic first.

You can also screw the Lexan sheet to the window frame instead of Velcro to get a more permanent solution, but first you will have to drill pilot holes.

What to do with Window Sill?

When they are in hurry to baby proof windows in all the rooms, parents usually forgot a piece of wood sticking out bellow, the window sill.

In case you have low window you should check edges. If edges are forming a harsh point you surely won’t want your child to fall into the window sill and knock its little head. You can soften up harsh edges if you use the same corner cushions that are used on coffee tables.

These are not just a danger for your kid because of falling, but also because they can attract a child to climb on. It forms a comfortable perch for baby’s little feet and gives your child the opportunity to view through the window.

That is a dangerous place for any child to stand on. Fall through the window can be extremely dangerous as well as falling into the room, so there is no good reason for your baby to play on the window still.

In case you were reading this guide carefully, you should have already removed any furniture that can assist your baby to reach the window sill.

There are some parents who put uncomfortable objects like a carpet tack strips on the window sill in order to discourage their children from climbing. We are against any method that can cause baby’s pain, so we kindly ask you not to do it to your children.

Finally, it isn’t enough just to baby proof parts of your home, but also to teach your little one to act in a safe manner around it.
