Five stages of development

1) Stage 1: Infancy - This stage begins at birth and lasts until about 2 years of age. During this stage, infants are primarily focused on developing trust and forming attachments to their caregivers. They learn to rely on others for their basic needs and start to develop a sense of self.

2) Stage 2: Early Childhood - This stage lasts from about 2 to 6 years of age. During this stage, children begin to gain a sense of autonomy and independence. They start to develop basic problem-solving skills and language abilities. They also begin to explore the world around them and interact with peers.

3) Stage 3: Middle Childhood - This stage spans from around 6 to 12 years of age. During this stage, children continue to develop their cognitive and social skills. They become more adept at following rules and understanding concepts. They also start to develop a sense of industry and begin to form a sense of identity.

4) Stage 4: Adolescence - This stage typically occurs from about 12 to 18 years of age. During adolescence, individuals experience significant physical, emotional, and cognitive changes. They begin to question their identity and navigate the challenges of puberty and social relationships. They also start to develop their own beliefs and values.

5) Stage 5: Adulthood - This stage begins around 18 years of age and continues throughout one's life. During adulthood, individuals focus on establishing careers, forming intimate relationships, and building a sense of purpose and meaning in life. They also navigate important life transitions, such as marriage, parenthood, and retirement.
