Week 14

Laura is now in her second trimester! Our baby's crown to rump length is about 3.2 to 4.5 inches long and he or she weighs approximately 1 ounce now. Our baby is about the size of the average fist.

At this time, our baby's face is becoming more developed. The cheeks and bridge of his nose appear and the ears move from the sides of the neck to much higher on the head. The eyes continue to come closer together. A big development from this week onward is the development of lanugo. Lanugo is the fine hair that grows over almost our entire baby. The hairs grow in whirled patterns that follow the grain of his or her skin. These patterns later give way to our baby's fingerprints. The lanugo will be shed before birth and replaced by thicker, coarser hairs. Our baby's thyroid gland has matured and starts to produce hormones. If our baby is a boy, the prostate will appear. And the ovaries descend from the abdomen into the pelvis in baby girls.
The embryo`s soft cartilage is now being replaced with ` real` chalk bones. Our baby has eyebrows, but no eyelashes. Fine, light hair also begins to grow.
