Today I moved all of your 3-6 month pants out of your closet. Really they still fit you great in the waist, but are much too short, even to pass as capris. So now you are officially only in 9mo or larger pants! As for tops, 12mo or 18mo are ideal for your length. I just choose not to notice how baggy they are. Size 3 shoes still fit perfectly.
One thing can be said for staying little: you can wear the same clothes for years. And that translates into quite the wardrobe for my little fashionista!
