what is infancy in psychology

An infant is the extremely young progeny of a person. Although it is frequently used to refer to the offspring of any organism, the phrase is typically regarded as interchangeable with baby or brain when used with humans. The word “toddler” is used alternatively when a newborn baby starts to move.

Although terminology may differ between birth and one year of age, or even between birth and two years of age, the word “infant” is commonly used to refer to young children between the ages of one month and twelve months. Infants that are just a few days, minutes, or even hours old are considered newborns. In health settings, the word “newborn” or “neonate” pertains to an infant within the first 28 days of life; this includes full-term, preterm, and post-mature newborns. The word “fetus” refers to an unborn child.
