#AskTheExpert Good morning sir, my son is 4 months old his present weight is 5.76kgs birth weight is 2.2kgs. it's normal weight or he should grow more. please clarify

A. Hi mam in the first 3 months, babies put on about 800-900grams each month. From 3-6 months, weight gain reduces to 1/2 kg/month. from 6-9 months, it becomes 1/3, and for 9-12 months, it becomes 1/4 kg. the birth weight doubles in the 4th month and triples when they reach 12 months of age.
