WHO Growth Standards

1-month weight increments (g) GIRLS Birth to 12 months (percentiles)

To find out daily growth expectations, find your baby's percentile in the column and the number of grams he should be gaining during his current month of age. Divide that number by 30 to convert it from a month of growth into daily growth expectations. To covert it into ounces, divide by 28.
