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.
My understanding is that the target 1oz (20g) weight gain per day is an average that is actually based upon bottle fed babies, because powered milk takes longer to digest it therefore also is in the babys system longer to convert into fat which is why a bottle fed baby gains weight quicker.
