Week 36 of Pregnancy

Baby Size Comparison in Week 36

In week 36 of pregnancy your baby measures about 47 cm long and weighs about 2.6 kilograms: roughly the size of Head of romaine lettuce. Remember these are approximate averages from standard growth charts; every baby grows at their own pace, and your doctor follows your baby's personal growth curve across visits, not a single number. If an ultrasound measures a little bigger or smaller than average, that is usually normal as long as growth continues at a steady rate.

Baby Development in Week 36

The fetus gradually sheds the vernix and the fuzz (lanugo), which it swallows with the amniotic fluid to become part of the first stool (meconium). Most fetuses now settle head-down in preparation for birth, and the head gradually descends toward the pelvis.

The lungs are ready and the brain continues growing, and the kidneys and liver work efficiently. The digestive system is ready to digest the mother's milk. The bones harden except the skull bones, which stay flexible. The weight is about 2.6 kilograms and the length 47 cm. From now on, the weight gain is mostly what grows, with most organs complete.
