Final answer:
The stage from birth to 2 years old is called infancy, covering the first year and marked by rapid growth and development. After the first year, a child enters toddlerhood, which lasts until about age three. Infancy is the correct answer to the question.
Step-by-step explanation:
What is the Stage from Birth to 2 Years Called?
The stage from birth to 2 years old is known as infancy. Infancy is the first year after birth and a time when a baby experiences rapid growth, doubling in length and tripling in weight. This period is crucial for physical, motor, sensory, and cognitive development. Following the first birthday, a child enters early childhood, starting with toddlerhood, which lasts until around the age of three.
Understanding Infancy and Toddlerhood
- Infancy covers the initial year of life and is marked by fast physical growth and developmental milestones.
- Toddlerhood spans from one to three years of age where growth remains swift, but not as pronounced as during infancy. Toddlers learn to speak, use simple sentences, and develop motor skills significantly.
In conclusion, the correct answer to the question posed is option 1) Infancy, which is the term for the stage from birth up to two years of age, focusing particularly on the first year of life.
