hlw doctor my baby girl is 15 months old her height is 74cm and weight is 8.5 is it normal or not

A. At 15 months, an average baby girl's weight typically ranges from 8.5 to 11.5 kg and height from around 74 to 80 cm. Your daughter’s height of 74 cm is within the normal range, though on the lower side, and her weight of 8.5 kg is at the lower end of the average. If she is active, meeting developmental milestones, and growing steadily on her growth chart, it may still be normal. However, if her weight or height has stalled or declined, or if she has poor appetite or frequent illness, it’s best to consult a pediatrician for assessment and nutritional advice.
