In order to raise a child who can say hello, first of all, the mother should give a nice greeting!

Even though the children around me can greet cheerfully ...

It feels great to be greeted cheerfully. Some children can greet innocently and cheerfully regardless of who he is, while others turn down even if they are greeted (children who cannot return the greeting). As a parent, you want to say, "Greetings should be fine."But it's okay. A child who is greeted and looks down is not unable to greet, but "I want to do it, but I just don't have the courage to do it now." She can greet her well in her heart. In that case, let your mother keep setting an example. When the mother treats the people around her with a smiling smile, the child also wants to say "I want to say hello like a mother." I'm sure you will be able to say hello like a mother if you notice.
