Upon reaching a certain age, each child begins to lead, if this can be called, an independent lifestyle, which will come in handy in the future. Children begin to help parents around the house, in the kitchen, and also begin to send them to the store for minimal purchases. Someone considers it right, and someone believes that a store is not a place for children.
By and large, the problem can only arise in the fact that the child will buy something wrong, spend more money than necessary or deceived him. Well, an adult can also deceive, and purchases that they make may also not always be correct. Therefore, this way cannot be reasoned.
The store develops the child to some extent. Thus, the child learns independence and a sense of responsibility. Even if he bought something wrong for the first time, there is nothing wrong with that, no one has died yet. But you explain his mistake for him and next time he will try to make everything possible from him so that such problems no longer arise, which is extremely important.
So it turns out that the trip to the store, it would seem, is a completely ordinary phenomenon, can do great benefit. And you should not think about potential risks, because, all the same, you will not protect either yourself or your child from them. Give him freedom and teach him from an early age to do everything yourself and right.
