Week 15

I'm in the middle of my 15th week of pregnancy! Here's what the baby's doing:

Week 15
You are 15 weeks pregnant and your baby weighs around 2.47 ounces, or 70 grams. Baby's tiny heart is now pumping about 25 quarts of blood a day. And the skin that has developed is so thin, one could see through it to the blood vessels inside! By birth, baby's heart will be pumping around 300 quarts of blood a day!

Baby's hair growth continues this week both on the head and the eyebrows. If your baby is going to have dark hair, hair follicles can start to make the pigment that will color baby's hair. Baby's ears are nearly in position by now, however they are still sitting a bit low on the head. Inside, the bone and marrow in the skeletal system are continuing to develop. As well, muscle development continues. In fact, your baby may even be able to make a fist and bend his or her arms at the elbows and wrists!
