Your preschooler is constantly evolving and now is a part of the regular world pretty concretely. As a result, it is important for you to work on their language so that they maintain a good image. You need to rear your kid to be a polite person and ensure he has good and decent words in his vocabulary.
What you need to know
Improve their language by teaching them words that are refined. The first step should be to make the child learn from their environment. If there is a chaotic environment at home then it will surely affect your kid’s language and behaviour. Maintain a decent environment at home so that the little one can adapt positive habits. Teach the kid the correct use of ‘Please’, ‘Thank You’ and ‘Sorry’.
If they pick up any foul word then immediately forbid them from using such terms. Teach the kid about sharing and caring for other people. This would automatically affect their language and actions. Respecting elders, greeting friends at school etc are some important things which must be taught to the kid for them to develop polite speech.
