Children at all times remain gullible and naive. They find it difficult to distinguish between a truly "good" and "evil" person. For this, they have a single, but very unreliable criterion - a smile: the baby perceives a smiling person as kind. Unfortunately, adults are well aware that this is not always the case. In order to protect children from violence until they have the appropriate experience, parents need to teach them one simple truth: there are good people, and there are bad people, from whom you need to stay away.
When you read a book with your child or watch a cartoon, focus his attention on the fact that in life, as in any fairy tale, there is also good and evil, give simple examples.
Establish strict rules about strangers and enforce them. First of all, clearly define the border between "friend and foe". Explain to your child that a stranger is any stranger. It doesn't matter who he thinks he is and how he behaves.
Discuss the second rule: before communicating with a stranger, you need to ask permission from loved ones. Mark a clear circle of faces - mom, dad, grandmother, etc. Strictly enforce this rule. Even if an old school friend comes to you, whom you have not seen for many years, and your little one sees him for the first time, make sure that the child asks permission before accepting a gift or going with him for ice cream. It doesn't matter that you trust a friend, but without such consistency in the requirements, the baby will not perceive this as a real rule.
Teach your child a simple but key phrase: "I don't know you, you are not my mom (dad)." Even if you bring up politeness and goodwill in a child, explain that he has the right to refuse any adult, especially a stranger.
Explain to the child, leaving him at home alone, that the door should not be opened by anyone except mom, dad, grandfather (clearly indicate the circle of faces). You can teach him, in case someone knocks and asks the parents, to answer that dad cannot come up yet, because he is sleeping or busy, etc.
Determine and discuss with your child all possible boundaries of danger. For example, you cannot go with a stranger, no matter what he offers: candy, ride a carousel, see kittens, go to meet mom, etc. This means that any stranger with any suggestions and requests must be refused before receiving permission from mom or dad.
When your child is 6-7 years old, start teaching him to understand people, passing on your own experience. Discuss situations from life, analyze the heroes of children's films and works. As the baby grows up, he accumulates his own life experience, gradually abandon rigid rules, replacing them with more flexible ones.
