Fans and Lights

Babies who aren't old enough to interact with objects yet will likely enjoy sitting and looking at lights or fans on the ceiling.  Watching fan blades whirling around and around sure beats watching a boring, unmoving blank ceiling and who doesn't like to stare off into lights until it hurts your eyes and you have to look away?  Am I right?  Obviously, to be good protectors of your little ones, please don't let your babies stare into the lights too much, as this can cause eye damage.
