I've seen them....well looked at them but decided no because of the sizing. When a clothing article has a 10" give or take sizing there's too much room for errors. The clothes is either going to be too big or too small.
I wear an XL in Tykables snappies and the fit perfectly. diaperu sizes have an 10" in-between sizing. There's no way I'm going to go thru the trial and error cycle again. I tried it with Bambino onsies and now I got an XL onsie in my stash that fits like a small. I ordered according to Bambino size chart but that chart was way off. Nothing like wasting money.
I'll stick with Tykables because the snappies are consistent and tried and true.
