My son is 10 months old and he is good in health but not gaining weight.... Is there any food or powder for weight gain

A. hi sir , babies weight gain depends on their birth weight usually they gain triple their birth weight by the age of 12 months so ideally , your child should have weight between 5.2 to 7 kg please ensure first ,that your child weighs enough or not. if a child weighs within the range, nothing to worry about it
