Different Ages And Stages 

Different ages and stages refer to the various developmental milestones and characteristics that individuals go through as they grow and age. These milestones can be broadly categorized into several stages, namely infancy, childhood, adolescence, adulthood, and older adulthood. 

Infancy typically spans from birth to around 2 years of age. During this stage, infants experience rapid physical and cognitive growth. They learn to grasp objects, crawl, walk, and develop basic language skills. They are highly dependent on caretakers for their needs and require nurturing and care in order to thrive.

Childhood generally encompasses the ages of 2 to 12 years. This stage is characterized by significant physical, cognitive, and social development. Children refine their motor skills, expand their vocabulary, and develop more complex thinking patterns. They engage in play-based learning, form friendships, and acquire social skills.

Adolescence, typically starting in the early teens and lasting until the late teens or early twenties, is a period of tremendous physical, emotional, and social changes. Adolescents experience puberty, undergo rapid physical growth, and grapple with identity formation and independence. They may also navigate complex social relationships and face challenges in decision-making and peer pressure.

Adulthood usually begins in the mid-20s and extends throughout the middle years of life. This stage is characterized by increased stability and responsibilities. Individuals establish careers, form long-term relationships, and may start their own families. They typically experience personal and professional growth and take on significant roles within society.

Older adulthood, also known as late adulthood or elderly years, typically starts around the age of 65 and continues until the end of life. During this stage, individuals may experience physical decline, including changes in mobility and sensory functions. However, they also have the potential to maintain a fulfilling life. Older adults often reflect on life experiences, enjoy leisure activities, and may face challenges related to health and social connections.

It's important to note that while these stages provide a general framework, individuals may experience variations in their development and progression through these age ranges. Additionally, factors such as culture, environment, genetics, and personal experiences can influence the timing and extent of developmental milestones.
