my son is 3 yr old but he talk only single single word didn't make sentences, he watch TV more than 4hr .he is understanding but no response, less eye contact. what can I do for this problem

A. Ma’am it is not a very good sign that your child is not making proper eye contact or not able to talk or communicate properly because because your child is having extremely high amount of screen time which is not good which actually the verbal growth of the child so communicate more and more try to make it zero screen time and take a child to the park and garden every day for two hours to channelise the energy of the child and check with your doctor because it is less I contact could be associated with deficiency of iron
