Your baby’s sensory development is exploding! Her brain is designating specialized areas for smell, taste, hearing, vision, and touch. Some research suggests that she may be able to hear your voice now, so don’t be shy about reading aloud, talking to her, or singing a happy tune if the mood strikes you.
Your baby weighs about 8 1/2 ounces and measures 6 inches, head to bottom — about the size of a large heirloom tomato. Her arms and legs are in the right proportions to each other and the rest of her body now. Her kidneys continue to make urine and the hair on her scalp is sprouting. A waxy protective coating called the vernix caseosa is forming on her skin to prevent it from pickling in the amniotic fluid.
Baby’s now the size of a mango!
Vernix caseosa, a greasy white substance made of lanugo, oil, and dead skin cells (yum) now coats baby’s skin, shielding it from the amniotic fluid. (Picture yourself after a nine-month bath, and the need for protection makes sense.) You might get to see the vernix at birth, especially if baby is premature.
Week Nineteen: Genitals recognizable
- You are 19 weeks pregnant. (fetal age 17 weeks)
- Fetus is around 6.5 inches (17cm) and 9 ounces (250gm).
- Your placenta continues to grow and nourish the baby.
- Features of your baby’s heart, should be visible during an ultrasound.
- Your baby’s genitals are distinct and recognizable.
- Scalp hair has sprouted and continues to grow.
If baby is female the uterus starts to develop, the vagina, uterus, and fallopian tubes are in place. Females have a limited supply of eggs in their lifetime. At this point your daughter will have 6 million eggs. This amount decreases to approximately one million by birth. If it’s a boy, the genitals are distinct and recognizable. Even if the sex looks obvious, ultrasound operators have been known to make mistakes.
Baby’s legs are reaching their relative size and with the increase muscle development occurring as well, you will start feeling much more than tiny flutter kicks soon. If you have not felt movement yet, you will soon. Your baby will increase its weight by more than 15 times between now and delivery.
Your baby’s size is around 6.5 inches (17cm) and 9 ounces (250gm).
Your baby’s skin is now covered in vernix, a white waxy substance. It helps protect her skin from becoming waterlogged while she’s immersed in the amniotic fluid, and also from scratches inflicted by her wayward fingernails.
At 19 weeks, your baby’s sensory development is at its peak. The nerve cells that will control all of her senses are developing in specialized areas of her brain. The reproductive system is complete now, too. As your baby’s nervous system develops, she’ll master increasingly complicated movements, twisting, turning, stretching, grasping and even doing somersaults. If you press firmly on your bump, she won’t just sense the pressure but will actually move away.
