How often do you bathe your baby?

DS is ten days old.  His umbilical cord still hasn't fallen off.  SO he hasn't had a real bath yet.  We have been sponging him off and washing his hair every two to three days.  I feel like that is a long time between baths, but he isn't really dirty.  And he does not like his baths.  How often are you supposed to bathe a newborn?
