Fetal Weight Standard

At week 36, your baby may 'drop' down into your pelvis—a process known clinically as engagement or lightening. The head settles into the pelvic brim, readying for birth.

The baby's digestive tract is filled with meconium. Most of the lanugo hair and vernix coating has shed into the amniotic fluid, which the baby swallows as part of digestive maturation.
