Any other prefold Mamas with a big boy. We use mostly green mountain diaper prefolds. My son is 14.5m, about 25 lbs, and the brown edge (large) barely for around his hips. I just got some green edge and those will hopefully last several months, but I don't imagine they'll last until he's 2. I know that's as big as GMD goes, but if there another company that makes bigger prefolds? Do I just get flats and use inserts? Or do we try to potty train when he out grows the XL? Any advice would be helpful
