I have a twins baby , baby boy & baby girl at their birth time baby boy weight was 2.200kg and knows he was 3 months 20 days old his weight was 5 kg and the baby girl weight was 1.800kg when she born and know she is also 3 months 20 day old and her weight was 4.300 did there weight was growing good according their months

A. If the kids were not premature then the child is expected to gain about 500 g in a month by completing the age of four months put your kids should be 2 kg more than the birth weight so if you evaluate the weight current weight on the basis of the birth weight and the air it is better than the expectation of both your kids are taking proper weight
