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.
The guidelines for pregnancy weight gain are determined by the Institute of Medicine (IOM). Healthy weight (BMI of 18.5 to 24.9): If your pre-pregnancy weight was in the healthy range for your height when you conceive, you should gain between 25 and 35 pounds. For the optimal growth of your baby, aim to put on 1 to 5 pounds in the first trimester and about 1 pound per week for the rest of your pregnancy.
