Month 5

Hair is beginning to grow on your baby's head and lanugo, a soft fine hair, covers his or her shoulders, back, and temples. This hair protects your baby and is usually shed at the end of the baby's first week of life.
Your baby's skin is covered with a whitish coating called vernix caseosa. This "cheesy" substance, thought to protect baby's skin from long exposure to the amniotic fluid, is shed just before birth.
You may begin to feel your baby move, since he or she is developing muscles and exercising them. This first movement is called quickening.
By the end of the fifth month, your baby is about 10 inches long and weighs from 1/2 to 1 pound.
