Twenty-three Weeks Pregnant

I am more than 11 inches long and weigh just over a pound. I may be able to feel Mummy's movements now, so put on some tunes and dance around the house. I look red now due to blood vessels showing through my transparent skin. My true skin tone will develop over the course of my first year. Blood vessels in my lungs are developing to prepare me for breathing, but complete lung development will take many more months. The lungs are the last organ to fully develop. I can swallow, but I normally won't pass my first stool (called meconium) until after birth. Loud noises heard often in utero — such as music or the roar of a vacuum cleaner — probably won't faze me when I hear them outside the womb.
