my baby is 8 months old..but still her weight is 4 and half kg..she is preterm baby..her birth weight is 1 and half kg, I'm worried about her weight and growth

A. hello since it is a Premi baby there can be a delay and nothing to worry and if the baby s active and taking the feed well and taking the food well then nothing to worry and any concern then it would be better to check with your doctor and she can guide you accordingly
