My friend down the hall, Kristen, is 3 and in preschool. At her preschool, stick-on earrings are all the rage. She shared a pair with me one day and I was so excited. Mommy found some gemstone sticker earrings, and now I select a new color and shape every day. I look forward to putting on my earrings every morning - and today, I chose green hearts! They don't necessarily have to match my outfit - the colors and shapes just have to strike my fancy.
