neonatalinfantile
Neonatalinfantile is a term used to describe the period encompassing the neonatal and infantile stages of human development. The neonatal period, also known as the newborn period, typically spans the first 28 days of life after birth. This is a critical time for adaptation to life outside the womb, with major physiological changes occurring. Infants are born with a range of reflexes and are highly dependent on caregivers for survival and well-being.
Following the neonatal period, the infantile stage begins, usually considered to last from one month of age
