Baby measures about 3.2 to 3.5 inches (7.6 to 8.9cm) from crown to rump and weighs about 0.9 ounces (25g). Your baby is now nourished by the placenta.
The face is developing and the cheeks and the bridge of baby's nose are appearing. The ears are moving from the sides of the neck to higher on the head and the eyes are moving closer together. Your baby's external genitals are now distinct and may be recognized on an ultrasound. Your baby will move away from stimuli near your tummy, such as noise and light.
Your baby's eyebrows have formed and a small amount of hair, called lanugo, has appeared all over the body. Lanugo, which will be shed before birth and replaced with the hairs with which your baby will be born, is thought to have a protective function.
Insulin is present in your baby's pancreas. Some bones may be well outlined. Your baby's thyroid gland, already developed by this week, begins to make hormones.
Baby boys begin to develop the prostate gland at this time and the ovaries of baby girls descend from the abdomen into the pelvis.
