if u have a baby up to 6lb its classed as very small, if u have a baby between 6lbs 9 and 8lbs 12 its classed as average and anything over 8lb 13 is classed as large, so everyone lets here what size babys you have already had, my 1st was a 8lbs 1 ie classed as average size my 2nd was 2 weeks early and 9lbs 2 so classed as large esp for 2 weeks early hate to think if had on time. this is what i have just read Fetal macrosomia has been defined in several different ways, including birth weight of 8 lb 13 oz to 9 lb 15 oz (4000-4500 g) or, greater than 90% for gestational age. High birth weight (HBW), babies weighing over about 9 pounds (4,080g) fall into the 90th percentile for weight and are known as large for gestational age (LGA) babies. About 10 percent of all babies weigh more than 8 pounds, 13 ounces (4 kg). With about 1.5% of babies their birth weight was equal to, or was greater than 9 lb 15 oz (4500 g). Rarely do babies weigh over 10 pounds (4.6kg). Although most LGA babies are born at term (37-41 weeks of pregnancy), a few premature babies may be LGA.
