I'm never sure why the term is "bridezillas" when it really should be "mothersofthebrideandgroomzillas"! My wedding was a long time ago but I do remember the stress. My advice would be pick the really important battles to fight and let them get away with the smaller things.

If it makes you feel any better we were asked if we wanted our wedding filmed, we both said No, so my father-in-law went ahead and had it done anyway!

Just don't let it get to you too much. *hugs*
