twentieth week  

Emily is about 12 inches long and weighs about 1 pound. Her mother has definitely begun to feel movement by now. If a sound is especially loud, the baby may jump in reaction to it. Her mother will also feel Emily's hiccups. She might sit upright with straightened back and legs crossed in a yoga-like position or she could be lounging back with her arms folded under her head. She may pedal her legs, make crawling movements, roll over or turn somersaults.
