neonatal period

in human development, the period from birth to approximately 1 month of age for infants born after a full-term pregnancy (for infants born prematurely, the period is longer). Among nonhuman species, the neonatal period varies depending on the species. For example, in dogs the period extends from birth to approximately 12 to 14 days of age; for some rats it lasts approximately 21 days. See also developmental levels.
