One-Word Stage

During language development children go through stages during which their language gets better and better until they can finally speak fluently. The one-word stage, as the name implies, the stage in which children speak mainly in single words. For example, during the one-word stage a child isn't yet able to say "I want milk" so they say "milk". This stage occurs from about age 1-2, and then gives way to the two-word stage (seriously...it's true).
