From My Baby This Week:
Your baby is more than 11 inches long and weighs just over a pound (about as much as a large mango). She may be able to feel your movements now, so put on some tunes and dance around the house. No matter what race your baby is, she looks red now due to blood vessels showing through her transparent skin. Her true skin tone will develop over the course of her first year. Blood vessels in your baby’s lungs are developing to prepare her for breathing, but complete lung development will take many more months. The lungs are the last organ to fully develop.
