my son is 4 months 7 days old.and weight is 8.4 kg.is this normal.he is on exclusively breastfeeding.his birth weight was 2.88kg

A. Actually the weight is on the higher side even if we calculate as one KG gain in a month then also your child should have been somewhere around 7 kg so little on the higher side but the only relief is that your child is an exclusive breastfeeding which is totally healthy so nothing to be worried as of now
