Week 15
Baby
Your baby's legs have grown longer than the arms and the body is now longer than the head. Even though you still may not notice, he is moving those arms and legs very often, even bending his knees and elbows! His skin still remains very thin and translucent, so thin blood vessels are visible. The 3 small bones in his middle ear have begun to harden. Fingernails and toenails are beginning to grow, as are his eyebrows. The little hairs on his head are even sprouting up, although the color and texture generally will change after he is born. Many of his major organ systems are continuing to grow and increase capacity. His tiny little heart is now able to pump about 25 quarts of blood per day. When he is born, it should pump somewhere around 300 quarts per day. This week, he weighs almost 2.5 ounces and is an amazing 4 inches long, about the size of an apple.
Note: Every baby develops a little differently — even in the womb. The information listed on this site is designed to give you a general idea of your baby’s current development.Mommy
You are well into your pregnancy at this point, and may even start to notice some different pregnancy symptoms such as a nosebleed or a stuffy nose. The nosebleeds occur as a result of increased blood volume and blood vessel expansion in the nose. The stuffy nose is actually a condition called "rhinitis of pregnancy" and can be blamed on hormonal changes, combined with increased blood flow to your mucous membranes. Wondering when the baby will start jumping around in there? Most mothers will feel their baby move sometime between 16 and 22 weeks. Repeat mothers tend to feel them sooner than a first time mom. This is because a woman who has experienced the feeling before is more likely to notice it and distinguish it from other belly rumbles. Also, a smaller framed mom may notice the movements sooner. You are most likely to notice some of his first movements when you are resting or sitting still. You may not even the first movements are actually coming from the baby, you may dismiss them as gas or hunger pangs. But once he starts moving more often, you will be sure to tell the difference.
