How does the baby grow?
From head to butt, the baby is about 14cm long and weighs about 190 grams (about the size of a bell pepper). The baby often moves their arms and legs which moms will notice more in the coming weeks. The baby’s blood vessels can be seen through the delicate skin, and the ears are now in their place although they are still facing a little away from the head. A layer of protective fat begins to form around the nerves, which will continue for a year after the baby is born. If the baby is a girl, her uterus and fallopian tubes have formed and are in place. If the baby is a boy, his genitals can be seen clearly but can still be covered when moms have an ultrasound.
Changes occurring in the mother’s body during the 18th week of pregnancy
At this time, moms always crave for food, which is fairly common. Moms should choose nutritious foods instead of calorie-free foods like chips, candies, and other sweets. It is also recommended to choose more comfortable clothes to fit the growing waist.
Moms’ cardiovascular system is undergoing major changes; the blood pressure may be lower than normal during these three months. Therefore, moms should not stand up too quickly while sitting to avoid dizziness.
From now on, it’s best to lie on the left side – or at least slightly on one side. (When lying on the back, the uterus may compress against a vein, leading to a decrease in blood flow to the heart.) Placing a pillow behind the back, under the hips or thighs is a good idea.
