It is of great significance that people get their apartments and their houses baby proofed. This means that when their kids are quite young, let us say that they crawl, the toddlers that are there. These are the kids in whose age they do not have a sense of responsibility and a lot of curiosity to start with. This is why they go and do everything that their parents tell them to not do. They are curious to know what is down the stairs although the parents are stopping them from going there because of the fact that the kids might fall down the stairs and hurt themselves. Whereas the kids take it as a permission to go down the stairs. They fall, but never learn until they are old enough to understand that it is not good for them to go down there while they crawl for that matter.
They are curious at all times. The kids have a nature to go and do the exact same stuff that their parents have been telling them to ignore and not go near to. All parents want good for their kids and so they stop them from going near the stairs. This is a sign for the kids to try going there because they have been stopped to do so. A baby gate would take care of the fact that even after the kids not understanding the motive of their parents behind stopping from going near the stairs, at least the gate would slow them down. The kids would have to spend some time trying to find a way to surpass the gate. And that is enough amount of time that parents need to worry that their kids are on to something and that they need to do something about it. This is when the parents enter and stop their kids by taking them away from the stairs. This is one way in which the baby gates are just very helpful for the kids to not getting injured because they did not fall off the stairs as they had no time to jump over the stairs at this point in time now.
There is a trend that people follow that is that a person needs to have baby safety gates for stairs installed to make sure that the kids do not hit the wall even when they fall off the stairs, the injury is not as bad as it could have been. This is to make sure that the kids do not fall off the stairs and are safe at all times too even if they fall as they do not hit the wall then.
