Should parents try to teach their children before they go to school? What things should they teach?

Before going to school, we should teach basic manners to our children. To be a loved friend or student, knowing basic manners is necessary. For example, they should greet teachers and friends with a smile in the morning. They shouldn\'t talk loudly when teachers do a class. They should lend their goods when friends don\'t have them. In other words, they should be socialized before going to school. To make them socialize, we can send our children to a kindergarten or a church. In the progress of making friends, they can be trained in basic manners. Also, I recommend letting them read a book every day. The habit of reading a book help with understanding when they will study in school later. A person who knows a lot of vocabulary in their native language can learn and understand other languages more easily. So, instead of teaching English to children, the habit of reading a book is more helpful for their future.
