Greetings. He was taking lots of idli dosa. Only since a week he is not eating. Relax . It happens sometimes. Now concentrate. It is difficult to believe that a small baby understand emotional turmoil. Never shout, or argue or abuse in presence of your child, they can not understand and become victims.  Offer them a very happy healthy emotional environments otherwise they develop behavior problem. Follow immunization. Take care of mosquito to prevent malaria and dengue. Observe all precautions to prevent Covid19. Make them active and keep them socially active and mentally challenged. If any problen consult again with prior appoitment.

This phases of not eating are temporary and common at this age. The growth rate is lesser now. He will start eating soon.
