My son is 2 yr 10 months old & he is not properly talking. He speaks only single words. Can you suggest me what should I do?

Spend more time to tell him stories, ask him questions and encourage him to tell you more. Perhaps a smile, a nod, a thumbs up from you or his audience would encourage him to reply with more words? Watch for his reaction to see what prompts him to smile or frown, and encourage him to share with you why he is feeling thus. All the best :)
