Hi welcome to Healthcaremagic
The weight of the baby is within the normal range... The normal
weight gain of baby is first 3 months around 30g per day..,next 3 months is 20 grams per day., at the end of 1 year ., the normal weight gain will be 3 times the
birth weight... after 6 months , you need to wean the baby by supplementing with smashed vegetables., fruits ,
rice ganji... not to worry about the weight or growth..
Hope I have answered your question..
Takecare..
