I am so frustrated. I started DD in size small Fuzzi Bunz when she was 4 months old. They have been awesome, but now she's 8 months old and they're way too tight, leaving horrible marks on her legs. The problem is that the size mediums are still too big. She's having leaks and blow outs which I never experienced with size small. Has anyone else had this problem? I don't know what to do while we're waiting for her to grow into the mediums. Any suggestions?
