S.P.
Special times need not be pricey. Perhaps you could take her out for a doughnut or make waffles together. My favorite cake was one with a doll sticking out of it, the cake being the lower half of the dress. Even if you are not inclined, you could make it using a bowl to bake the cake, frost it, then let her add sprinkles and ribbons(fruit by the foot). Focus on showing her she's special and she will have a great day.
