Week 17

Here's what's happening with our little one this week from babiesonline.com:

Your baby will begin to form fat this week. The fat begins to deposit under her skin and is important in heat production and metabolism. At delivery, fat will account for 2-6 percent of your baby's total body weight. This will help her maintain her body temperature when she is born. Your baby is approximately 5 inches long and weighs in at about 140-145 grams (5 ounces). This means that the baby now weighs more than the placenta.
Her movements become stronger and more frequent now. Reflex movements are fully functional as baby will regularly suck and swallow and loud noises outside the uterus may actually cause the baby to startle.

Maternal changes:

Your uterus has grown and is now about halfway between your pubic bone and navel. Your bodily secretions may increase due to the increased blood volume. So if you have increased nasal congestion or runny nose, increased sweating or increased vaginal discharge this is normal and nothing to worry about. Rest assured, this increase in body secretion will go away after the birth of your baby.
As baby goes through some growth changes (getting bigger and begins to add fat deposits under the skin) you may find yourself "growing" too. Average weight gain to this point in pregnancy is about five to ten pounds, but don't worry if you are a little off.
