19w 0d - "Pason" This Week

• Your baby weighs about 9 ounces (260g) and measures about 5.6 to 6.4 inches (14 to 16cm) from crown to rump.
• Her skin is thickening and developing multiple layers- the epidermis and the dermis, the deeper layer where it will form fat. Your baby is now also developing a waxy protective coating for her skin called vernix caseosa. The vernix protects your baby's skin which is continuously submersed in amniotic fluid. Vernix, which is particularly thick around the eyebrows is held in place by tiny downy hairs called lanugo.
• Your baby can now grip with her fists. Toenails and scalp hair are growing.
• At this point, it may be possible to determine the baby's sex by ultrasound, if the baby cooperates, but the ultrasound technician will rarely guarantee the sex based on the ultrasound results as mistakes are sometimes made at an early ultrasound.
• You can hear the baby's heartbeat with a Doppler ultrasound device or a stethoscope.
