Your baby now weighs about 12 ounces, and you may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges.

Others get busy during the day. See what your baby looks like now and find out how to cope with skin problems, what to do about varicose veins, and more at BabyCenter.com.
