I bought the generic 2-3T Walmart brand for my daughter (no cf, but small) and it was wayyyy too big. My best friend and my sister gave me some Disney character hand me down undies shortly after, and they run much smaller and fit fine for her too. I had an awful time finding pullups though, but finally settled on brand that both Walmart and Target sell. Of course, I can't remember the name <img src="i/expressions/face-icon-small-disgusted.gif" border="0"> , but I'm going to Walmart or Target today, and I'll look. All I remember is that they were a cheaper brand (a plus), and came in either an all pink or all blue package (meaning girls and boys of course <img src="i/expressions/face-icon-small-wink.gif" border="0"> ) and were one of the few I could find in the 2-3T that were small enough.
