A child's motor development increases with age, from gross motor skills to fine motor skills. A child's fine motor skills will develop better if they are practiced and perform the movements repeatedly.

The motor development of 3-year-old children is often lively and sociable. This is the age when children speak and have more complex actions. In addition, children also become curious, approachable to strangers and have richer imaginations.

The time when babies start to stand, walk, and sit up varies greatly. Some babies walk as early as 9 months old, while others wait until they are 18 months or older. So should babies start walking, sitting, or standing early?

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."
