A more throughout explanation: An infant is a person who is not of legal age, typically defined as someone under the age of majority, which is usually 18 years old. In legal terms, an infant is a minor who has not reached the age of majority and is therefore considered legally incapable of entering into certain contracts or making certain decisions without the consent or supervision of a parent, guardian, or court-appointed representative.
Example: The infant was placed in the custody of Child Protective Services pending further investigation into the allegations of neglect.
