Just a thought, but could be REALLY fun for your DD, and a record of her accomplishment...
Why not consider finding a red knit dress (maybe Hannah Anderson or Land's End has one?), then go to JoAnns, and find nice thick white knit (or go through your DDs old t-shirts - old navy-type quality so the red doesn't show through). Wash the dress first, twice (very important). While at joanns, look for the heavy duty iron on, new sew applique stuff - ask a sales person for help. Go home, and cut out exactly that many days worth of white circles (make sure you cut them so they'll fit right on the dress). Each day let your DD help you iron on a single circle on to the dress. Keep it hanging somewhere on a special hanger covered in clear dry cleaners plastic so she can see it, but not touch it. She can spend time counting the circles, looking at the calendar, and each day adding a new circle. When she's done - Voila - a very special dress that she can wear to have her picture taken with Minnie.
I would just like to say, there are days I wish I had a girl (to go with my boys).
