my baby girl is premature when she was born the weight is 2 kg but after few days her weight is 1.7 after 2 month she is 2.7 is it normal??

A. Maybe the child has lost a little weight due to jaundice because during the time of jaundice it’s common for kids to lose their weight about hundred or 200 g or so but if from 1.7 if you calculate the weight gain for two months this is very good minimum gain of 500 is excellent excellent for a child
