Your baby is really getting ready to be born. Every day in the uterus is said to be two less days your baby would spend in the hospital at this point. Red blood cell production is done entirely by your baby’s bone marrow. Amniotic fluid is still present and your baby urinates into it daily, about a half a liter of urine a day.

The baby's irises can now dilate and contract in response to light. He or she opens and closes their eyes at will. Even the finger nails reach the end of the fingers. Some babies might even need a nail trim at birth! Your baby may have a lot of hair on their head or none, both extremes are normal.

The weight gain has been fairly incredible recently. Your baby has put on about 2 pounds of weight, mostly fat and muscle tissue, since last month, bringing the total to an average of three pounds eleven ounces (1.7 kilograms), and measurements to 40 cms or 15.8 inches!

The eighth month may seem like you've reached the end. While it's true you only have about eight weeks to go, they can feel like long months. Make the most of these months by staying active and getting out. This will help you feel physically and emotionally better. Don't forget to start planning for a temporary worker if you work, and for your maternity and/or paternity leave.
