what is considered low birth weight for baby
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. One third of babies born with a low birth weight are also small for gestational age. Other definitions include Very Low Birth Weight (VLBW) which is less than 3 lb 5 oz (1500 g), and Extremely Low Birth Weight (ELBW) which is less than 2 lb 3 oz (1000 g).
