Second Trimester
1. In the brain, nerve cells are forming and moving from the central to the outer areas. As yet, any neural activity is still very immature.
2. The skin is quite smooth and has a reddish tinge, since there is very little underlying fat.
3. The gut is too immature to function properly but it can take in the tiny amounts of amniotic fluid that the baby swallows at infrequent intervals.
4. At 16 weeks the average crown to rump length is 3.4 in (8.7 cm) and the average weight is 1.52 oz (43 g).
5. Greater mobility in the hands means that the baby is able to suck her thumb.
6. Facial muscles have developed enough for the baby to make faces, such as frowning, although she has no control over her expressions.
Some days, you'll take huge pride in your emerging belly, on other days you may sigh for the loss of a trim figure. Enjoy your changing shape-you'll probably find that your partner loves it, too. For many couples, this can be a time of increased interest in sex. If you have any emotional or physical worries, there'll be an opportunity to discuss them with your doctor. Another prenatal checkup is likely to take place this week.

Your baby todayIn this artificially colored ultrasound scan of the baby within the uterus, the spine shows up especially clearly. The two blue crosses, at the top of the baby's head and at his bottom, indicate where the rump to crown measurement is taken. read more

Your baby todayThe fingertips are prominent and the fingers still quite short. Each finger is separate and moves independently of the rest. This is the most comfortable position for the hand, with the thumb and fingers outstretched rather than curled into a fist. read more
You are 15 Weeks and 3 Days Pregnant
Your baby todayNow the toes are lengthening and a gentle arch to the foot is beginning to take shape. Your baby can grasp her feet at will but has difficulty bringing them up to her mouth: this is not a problem a little later in pregnancy. read more
You are 15 Weeks and 4 Days Pregnant
Your baby's skin is still transparent and there is little fat lying beneath it at this stage of the pregnancy. read more
You are 15 Weeks and 5 Days Pregnant
Your baby todayHere the baby is seen within the amniotic sac. For the first time, her head is smaller than her body, marking another developmental milestone. Having a large, heavy head is not a problem in the nearly weightless environment of the uterus. read more
You are 15 Weeks and 6 Days Pregnant
Your baby todayThe upper limbs are well differentiated into forearms, wrists, hands, and fingers; these develop at a faster rate than the lower limbs, a feature that continues even after the birth. read more
