36-40 Weeks Pregnant : Baby Development in The Third Trimester

36 40 Weeks Pregnant, Baby Development In The Third Trimester (14)

By 36 weeks your baby’s lungs are fully formed and ready to take their first breath when they’re born. They will also be able to suckle for feeds now, and the digestive system is fully prepared to deal with breast milk.

At 37 weeks, your pregnancy is considered full-term.

The baby’s gut (digestive system) now contains meconium — the sticky, green substance that will form your baby’s first poo after birth. It may include bits of the lanugo (fine hair) that covered your baby earlier in pregnancy. If your baby does a poo during labor, which can sometimes happen, the amniotic fluid will contain meconium. If this is the case, your midwife will want to monitor your baby closely as it could mean they are stressed.

In the last weeks, sometime before birth, the baby’s head should move down into your pelvis. When your baby’s head moves down like this, it is said to be ‘engaged’. When this happens, you may notice that your bump seems to move down a little. Sometimes the head doesn’t engage until labor starts.

The average baby weighs around 3-4kg by now.

The lanugo that covered your baby’s body is now almost all gone, although some babies may have small patches of it when they’re born. Due to the hormones in your body, the baby’s genitals may look swollen when they’re born, but they will soon settle down to their normal size.

Your baby is ready to be born, and you’ll be meeting them sometime in the next couple of weeks.
