Week 19 of Pregnancy

At 19 weeks pregnant, your baby is approximately the size of a mango, measuring about 6 inches long and weighing around 8.5 ounces. This week brings remarkable sensory development. The nerve cells responsible for all five senses are forming complex connections in the brain. Your baby can now taste the amniotic fluid, which carries flavors from your diet, and studies suggest babies develop preferences for foods their mothers eat during pregnancy. A white, creamy substance called vernix caseosa is coating your baby's skin. This protective layer shields delicate skin from the amniotic fluid and will help regulate temperature after birth. Your baby is developing brown fat, which generates heat and will keep them warm in the outside world. Lanugo, the fine downy hair covering your baby, continues to grow. Your baby's movements are becoming stronger and more coordinated, with distinct periods of activity and rest.

If your anatomy scan is this week, drink plenty of water beforehand, as a full bladder helps produce clearer images. Wear comfortable, two-piece clothing so you can easily expose your belly. The scan typically takes 30-45 minutes, and babies do not always cooperate with positioning. You may need to walk around or come back for a follow-up if the technician cannot see everything they need. For itchy skin, apply unscented moisturizer or coconut oil liberally and avoid hot showers, which can dry out your skin. Consider a maternity support belt if hip or back pain is increasing. Start thinking about your birth plan preferences, including pain management options, who you want in the delivery room, and your feelings about interventions. Begin researching childbirth education classes in your area.
