Explanation

A term neonate's birth weight typically doubles by 5 months, triples by 1 year, and quadruples by 2 years of age. These are standard growth milestones used to screen for failure to thrive in clinical practice. An average term neonate gains approximately 25-30 g/day in the first 3 months, 20 g/day from 3-6 months, and about 15 g/day from 6-9 months.
