I don't bother with Mother's Day, as my mother's birthday is quite often on the same day. That's one of the best things about my family, all their birthdays are at the time of other gift-giving occassions, so I can save SAVE SAVE!!!
My Dad's birthday is a few days after Christmas, so I save there, but the best one is, my sister's birthday is Father's Day. The savings on that last one are impressive.
