Sir my son is 20 months old but he hasn't started speaking yet Well he is very active, he understands everything but says nothing.

A. hi kids at age between 18 to 30 months who can understand what we say well , but having limited expressive vocabulary are considered as late talkers. but don't worry if a child is taking little bit time more. keep encouraging your child by talking with him more keep your child away from screens like tv mobile iPad etc
