"Your baby is about the size of a small bean, about a half an inch long, this week. If you could see inside yourself, you'd find the baby has an oversized head in proportion to the body. The facial features are forming with dark spots where the eyes are, openings where the nostrils will be, and pits to mark the ears. Protruding buds that will become the arms and legs are more noticeable now. The hands and feet look like tiny paddles. You can't hear it yet, but the heart is beating about 150 beats per minute (or roughly twice the rate of yours.)"
