We’re getting close! Your little one’s organs are completely developed and in the right place. The lungs and brain already work, so there shouldn’t be any issues if your baby is born before 40 weeks. After all, he/she probably weighs a little more than 3 kgs now. The thin hair that coated their little body for months is going away, just like the vernix caseosa, the waxy, creamy natural biofilm that protected the baby’s sink from amniotic liquid. A little bit of what’s left ends up in the intestines and forms the meconium, the thick, dark green substance that makes up the newborn’s first feces. The meconium is also made up of dead cells, amniotic liquid and residue from the liver, pancreas and gallbladder.
