my baby girl's birth weight was 3 kg now she is 4 years old and her weight is 5.5kg. Is this normal weight gain ? she has also started drinking less milk. but she is active and has no illness. I'm worried about her weight gain. and kindly share the weight chart.

A. hello 4 months baby do you mean and if baby is gaming a minimum of 600 grams to 800g per month then it is a good weight gain and it means the babies getting sufficient bm and is not a problem and if bm is not sufficient then give baby infant formula milk using a bpa free bottle like babyhug
