hello sir this is vihaan father here my baby boy was premature and that time his weight was 787 gram and now 5.7kg is this right calculation

A. Sir It is said that if the birth weight becomes three times by the age of 12 months it’s an ideal ahead of that and since you said that your child is born premature than the weight can be little less but it is quite less as of now also so please just discuss this issue with your doctor ones
