Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age.
A full term infant weighing less than 5 pounds, 8 ounces at birth is considered a low birth weight baby or small for gestational age of 39 weeks. Statistically speaking, approximately eight percent of all babies are this small at birth.
