A friend of mine recently emailed me this old wives' tale:
Thread a needle or use a necklace with a charm and have hubby suspend it above your belly. If the needle (charm) swings back and forth, a boy is in your future; if it moves in a circle, count on a girl.
We tried it this morning two times and it moved in a circle both times. Oh unscientific charm, are you telling us it's going to be a girl?
