First, physical development, at this stage, the child's body is developing rapidly. The following are some key development stages:

1. Fine movements: such as grasping objects and using tableware. Children at this stage can start using simple tools, such as pencils and erasers.

2, big muscle movements: such as jumping, running, kicking, etc. These activities can help children improve their sense of coordination and balance.

3. Language development: Children at this stage are learning to speak and develop vocabulary. They can understand and use simple instructions and begin to try to express their ideas in sentences.

Second, psychological development, at this stage, the child's psychology is also developing rapidly. The following are some key development stages:

1. Self-awareness: Children begin to realize that they are independent individuals with their own thoughts and feelings.

2. Social skills: Children begin to learn how to interact with others, including sharing, waiting for their turn and resolving conflicts.

3. Emotional understanding: Children begin to understand and recognize basic emotions, such as happiness, sadness, anger and fear.

Third, social development, at this stage, children begin to understand social rules and expectations more deeply. The following are some key development stages:

1. Morality and values: Children begin to learn and understand basic morality and values, such as honesty, fairness and respect for others.

2, daily life skills: children began to learn how to dress, eat and personal hygiene and other basic life skills.

3. Academic skills: Children begin to learn basic reading and writing skills, as well as mathematical concepts (such as counting and comparing sizes).

Understand children's learning styles and characteristics, create a rich educational environment, arrange children's daily life reasonably, and support children's needs to gain experience through direct perception, practical operation and personal experience.

Pay attention to the integrity of children's learning and development, pay attention to the mutual penetration and integration between fields and goals, and promote the all-round and coordinated development of children's body and mind.

Respecting the individual differences of children's development, each child shows certain stage characteristics in the development process, and the development speed and the time to reach a certain level are not exactly the same.
