Your Developing Baby, Week by Week

Your baby begins as a tiny cluster of cells, but during the nine-month process of pregnancy she becomes an amazing baby with facial features, a beating heart and kicking legs. Find out what's happening with baby's development week by week.

Your baby's previously see-through skin will now become opaque. However, it will remain wrinkly, red, and covered in vernix until more fat helps to fill it out. Also this week, he's fine-tuning his sense of touch (thanks to maturing brain cells and nerve endings). Your baby may experiment with these newfound skills by feeling his face or anything else he can get his hands on. This week, your baby's eyebrows start growing and hair will start sprouting on the scalp, but this varies -- your baby may grow a thick head of dark hair or he may enter the world bald.
