It is important to make sure that our kids are as safe as possible. This means that we need to do what is in our power to keep them safe to the best of our ability. There are a number of ways that we are able to do this. The thing that we should start with is teaching them the best way to answer the door.
The first thing that we need to tell them is that we do not just open the door immediately when someone is knocking or ringing the door bell. It is not uncommon for thieves to be so brash as to simply break their way through the moment the person on the other side opens the door. It is easier to do this when it is your kid answering the door.
The next thing that you need to do is teach them to ask who is on the other side of the door. They need to get an idea of who the person is and why they are trying to get in touch with the person of the house. If it is the pizza guy or even someone claiming to be a cop make them show you some proof.
This is when a peep hole is going to come into use. You want them to be able to use something that is going to allow them to see the person that is on the other side of the door and whatever they might try to be hiding. Of course in most cases the person will be who they say they are.
When you teach your kids how to safely answer the door they will be more aware of what could happen outside of the home. You should also try to teach them what to do is someone tries to snatch them on the street or when strangers come up to them. It will be safer for them that way.
