hi my baby is two years nine months active boy. he started speaking meaningful words since his one year five months n gradually talking meaningful sentences. but the problem is he is not understanding questions n answers. simply he repeated the question what I asked him.otherwise he says what he knows. means it is a slow process he learns conversation yet he is a fast learner regarding fruits name or months in a year. m worried about his language understanding. n till now he babble things. what to do. he understands but he is not understanding conversation like if I ask him questions he is not interested to give answers rather than repeat questions.
