I've got this great theme going for my baby's first birthday. It's Spring Fling. And my MIL took it upon herself to buy green mustaches for everybody there... An man I wrong for feeling annoyed considering this is a party for a girl and my theme is spring flowers and her colors are pink, purple and yellow. With small touches of green because it's St. Patrick's day?
