goodmorning doctor, my son will turn 3 years on March. still he doesn't say any sentences. but says many words. like appa, amma ,Chechi (sister),car, bus and much more. he recognises some colour also. he goes to play school. he sings rhymes. but not in the correct pronunciation.his elder sister 9 years old started to speak very early. should I give him any speech therapy or anything. what should I do to improve his communication skills.

A. Talk more to your baby. Ask a lot of questions to baby and wait to her a response. Encourage baby to give an answer. If baby tries to speak, wait listen and ask questions. Keep talking to baby and answer to all the babbles. Tell your nay everything you do like I'm taking you to park I'm changing your diaper. Just keep talking and respond to everything your baby babbles or speaks. By 9months to 1yeat they just say mama, papa. By 15 months will understand whatever we say and will observe more. By 18 months they speak few meaningful words amma appa papa mamma thattha.. After two years they make combinations of words like amma give, amma take, appa go, mama come.. Later they make sentences.
