Your little one is now roughly the size of an apple. She is about 4 inches long and weighs about 2 ½ ounces. Her legs are now longer than her arms and her bones are getting harder and stronger!
At 15 weeks, her skin is still thin and transparent, but she has developed a thin layer of hair to help protect her body. This layer of hair is called lanugo and it is present on every part of your baby's body, even her finger nails!
She is also moving amniotic fluid through her nose and upper respiratory tract. This action helps the primitive air sacs in her lungs begin to develop. And even though her eyes will remain fused shut until approximately 26 weeks, she can actually sense light in your womb!
Not sure why the weekly update says "she" I have gender as unknown on the Bump.com... ummmmmmmmmmmmm :)~
