Hi My baby boy is 3 months 8 days old and is on exclusive breastfeeding His birth weight was 2.9 kg And current weight is 4.7 kg Is it normal?

A. Your child has gained 1800 g in three months which is a very good weight gain so need not worry about the weight gain of your child it’s going very very well the minimum is expected 500 g of child gain better than that which is a good sign
