My baby is 15 months old and is an active baby but he is not gaining weight. His birth weight was 3.4 kgs but since a 2-3 months he is stuck in and around 9kgs. What should be done?

A. It Mostly could be due to some deficiency that your child’s body may be having which is why the way it has been stagnant for a certain point of time you should get a check with your paediatrician to have clarity about these things that start with supplements required
