How long is a child considered an infant?

In the context of childcare, an infant is typically defined as a child from birth up to one year of age. After this age, children transition into the toddler stage. Therefore, considering that the correct understanding of "infant" refers specifically to this first year of life, an infant is not considered to be up to two years. This stage is critical for growth and development, and understanding the developmental milestones associated with infancy is essential for caregivers and educators in ensuring that children are receiving appropriate care and support during this foundational period.
