I ordered a medium and large, they came in today, I decided to try the medium (which is only slightly smaller than tykables size 2) all I have to say is WOW, this diaper is comfortable and has taken 2 medium wettings so far, it's swelling up nice, seems to have decent wicking so far. I'm really happy with it. I think mediums are my size, the large is going to swallow me up tonight. The only thing holding me back from ordering a case is the price, I guess you can't have your cake and eat it to.
