Weight Gain Patterns. Between 1 to 4 months of age, an infant will generally gain 1 1/2 to 2 pounds per month, explains HealthyChildren.org, the website published by the American Academy of Pediatrics. From 4 to 7 months, his weight gain will slow to 1 to 1 1/2 pounds each month. A healthy baby boy will weigh between 14 1â2 and 17 1â2 pounds at 8 months; infant girls normally weigh about half a pound less than infant boys. By 12 months of age, a baby weighs about three times more than she did at birth.
