It differs from woman to woman, baby to baby. My baby has always been a few weeks larger than the projected size and weight. 1.5-2 lbs is a correct generalization. However, no one can REALLY tell how much your baby weights until he/she is outside of the womb. The weight of your placenta, amniotic fluid, maternal blood volume, breast tissue, ext all make up the weight you gain, and it's impossible to tell exactly what weight accounts for where. Not even ultrasounds are very reliable in predicting the weight of an unborn baby. A good way of predicting how much your baby will weigh at birth is by taking your birth weight, and your partners birth weight and finding an average of the two.
