G diapers leave marks?

[5littlesweeties]

Does this happen to any gDiaper users? I have some for ds and I rarely use them but everytime I try he gets a cut where the snaps are on his hips and it takes like a week to heal. He's a tiny guy too so it's not like they're too small. I have 6 mediums that I need to sell because I can't imagine these are comfortable at all. Does this happen to anyone else? Am I doing something wrong?
