My son is 3years old. Since we are a nuclear family with no help my son was exposed to tab/mobile phone a lot since the age of 8months. He ia 3years old now. He speak sentences with not more than 3 words. He is also fixed on talking only about 1topic. Like for e.g these days he only talks about washing machine and air conditioners. He doesnt reply to questions like what did yous tudy in school or what did u eat etc. He doesnt follow commands like go and give this message to so and so. I am very worried. The paedetrician had recommended speech therapy long back. The speech therapist i consulted even suggested behaviour therapy to begin with. What do u suggest. Kindly help me out. Regards, sweta
