my son birth weight was 2.3. he gained 750 g each month during first 6 months and 500 g for 6-8 months . now from 8-9 months he has gained only around 300g. his weight is 6.7 now. is it good or what can I do to increase his weight

A. Dear mum, weight of 6.7 kg is a normal weight for 8 months old baby, do not worry. After 6 months, the amount of weight gain reduces as compared to earlier. Baby should double the birth weight by 6 months and triple the birth weight by one year.
