Week 19 - Heather's Pregnancy Journey
Jun. 12th, 2005
12:30 pm - Week 19
About 17 weeks after conception
The baby will now be weighing about 8 ounces. If you are having a girl, her ovaries now contain primitive egg cells. Lanugo appears all over the baby's body. This fine hair will remain until birth draws nearer. Sometimes you can still see some on the baby's face and ears after birth. Permanent teeth buds are forming behind the already formed milk teeth buds.
Your baby is now covered with a waxy substance called vernix caseosa, which helps prevent delicate skin from becoming chapped or scratched. Premature babies may be covered in this cheesy coating at delivery. In the brain, your baby is developing millions of motor neurons, which are nerves that connect the muscles to the brain. As a result, your baby is now able to make conscious muscle movements such as sucking his thumb in addition to involuntary movements.
