The psychological development of preschool children at each stage has different points. That is the reason why parents need to spend a lot of time caring for and accompanying their children in the first years of life, because this will help children shape good personalities and be the foundation for future development.

Children aged 5-6 are in the stage of preparing for a change in their environment. At this time, children need to change their activities from mainly playing to studying to gradually get used to the primary school environment later. Children also need to practice doing daily tasks, developing their memory and observation skills.

One-year-old children are often focused on height, weight, and physical health rather than caring for and promoting motor skills. Many parents will think, "Children are still young, what do they know to teach?" but in reality, children of any age "possess abilities more wonderful than we imagine."
