#askdoctors my baby is going to be a year old in a week... they say the baby's weight should be the birth weight multiplied by 3 when they turn one... my baby is not... she is active... is there anything to worry about??

A. Hi yeah like 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.
