My baby is 5 months 20 days old and her weight is 6 kg. Her birth weight was 2.42 kg. As per doctors, she is underweight. What should I do?

A. I think your doctor is not very well aware about the fact that the child should gain minimum of 500 g in a month and should double the weight by the time of five months to 6 months of age and your child is already doing that already done that no problem it’s very healthy
