This week the baby is 6-7 inches long and weighs about 7-10 ounces. Baby is now able to make intentional movements, such as thumb sucking. The other developments occurring this week:
- The baby is developing millions of motor neurons, which are nerves that connect the muscles to the brain
- Parts of the leg have now grown in proportion to the rest of the body
- The skin is developing but is still transparent, appearing red because blood vessels are visible through it
- A creamy, white, protective coating called vernix begins to develop, which protects your baby's skin from its aquatic environment and helps prevent delicate skin from becoming chapped or scratched
- The placenta continues to grow and nourish the baby.
