Old Wive's Tale

I was watching 'Midwifes' on Discovery channel last night. And during the show, they were measuring this one woman's belly, trying to figure out what size the baby was going to be. Then the midwife asked her what size shoe she wore...she said that typically the baby will be +/- 1 lb from the size of the woman's foot. Guess what size I wear...a 9 1/2. Oh Bother...
