my baby is 3 month and 18 day now and its weight 5.4kg and she split milk even after burping . her birth weight is 3 kg and last two month weight gain is around 400-500gm is this normal?

A. Dear mum, a weight gain of 500 grams per month is normal, do not worry. Your baby has gained 2.4 kg in 3 months 18 days which is a normal weight gain. Baby should double the birth weight by 6 months or earlier.
