Late Teens Stage

(16–18 Years)

About This Stage

Late adolescence is a stage of consolidation. The emotional volatility of the early teen years settles, and your teenager starts to look and think more like the adult they are becoming.

The parents who navigate this stage best let go of control while staying deeply engaged — evolving from authority figure to trusted mentor without disappearing from the picture.
