I was born two weeks ago. I think I am two years old. I suggest you spend more time with your children. Companionship here refers to effective companionship, devotion, reading with children, playing games, etc. Increase the child's sense of security and let him know that attending early childhood classes does not mean being separated from his mother forever, which also helps to reduce his negative feelings about early childhood classes. Find out whether the early education teacher takes care of the children properly and see if it is because the children are not adapted to the curriculum.
