What is a key characteristic of neonates?

A key characteristic of neonates is that they are generally less than one month old. The term "neonate" specifically refers to infants who are in the first 28 days of life, a critical period marked by rapid development and adjustment to life outside the womb. Understanding this definition is important in medical and emergency settings, as care strategies differ significantly based on age and developmental stage.

The other options do not accurately fit the definition or characteristics of neonates. For instance, while some neonates may be premature, it is not a defining characteristic, as neonates can also be full-term. Likewise, neonates cannot walk; that developmental milestone is reached later, usually around the first year of life. Finally, neonates do not communicate verbally; their communication is primarily through crying and body language, as they have not yet developed the ability to speak.
