#asktheexpert my baby is now 5 month 12 days old her birth weight is 3.1 and now she is 6.4 is it normal..for first 3 months she gained about 800-1 kg now progression is less upto 500 gm is it normal

A. Dear mum, weight of 6.4 kg is absolutely normal for 5 months old baby considering a birth weight of 3.1 kg. Baby should double the birth weight by 6 months or earlier which your baby has already achieved. A weight gain of at least 500 grams per month until 6 months is considered normal.
