Many toddlers who barely speak at 18 months go on to speak clearly by 2.5-3 years. Some go from zero to full sentences in just two weeks. As long as your child responds to their name, understands what you say, follows directions, and points or gestures, there is usually no cause for concern. To encourage speech: narrate daily routines using simple words, do not give in too easily when they point, limit screen time, and read different types of books. If speech has not emerged at all by 24 months, a paediatrician consult is worthwhile.
