Right stage of child development is 

Child development occurs through distinct stages, each marked by unique physical, cognitive, emotional, and social changes. These stages help in understanding how a child grows and develops over time. 

Key Points

•  The appropriate stages of child development include prenatal and infancy.
• The prenatal stage refers to the period before birth, where the foundation for physical and neurological development is laid.
• The infancy stage follows birth and lasts until around two years of age, characterized by rapid growth, sensory development, and early learning through interaction and exploration.
• These two stages form the initial phases of human development and are crucial for later growth.

Thus, it is concluded that the Right stage of child development is Prenatal, infancy.

Hint

• Babyhood and childhood are both postnatal stages, but babyhood is often considered a part of infancy rather than a distinct phase in developmental psychology.
• Childhood follows infancy but does not include the prenatal stage.
