Hi MumOfThree! I do feel for you... Some suggestions on what worked with my three kiddos...I let them put stickers all over the "big potty" and their "little potty" and also let them decorate the potties using washable markers. We also role played a lot with my daughter putting her stuffed animals or dolls on the potty. I actually bought another potty so her stuffed animal/doll could "use" the potty at the same time as my daughter. Oh, we would hug the potty, talk to the potty as if it was real, we named the potty, sang to the potty, let her actually "clean" the potty with a spray bottle filled with water (she thought she was such a BIG girl doing this haha) Rewards worked great with my sons (matchbox cars) but not with my daughter. If you don't want to use candy because of her restricted diet, you could always use whatever else she is interested in. Another wonderful thing that worked is to carry the potty (and have a potty on each floor) wherever she was playing, so she wouldn't have to panic and race to the bathroom. You mentioned winter and freezing...That's exactly when I potty trained too. I just cranked the heat and let her run around naked all day until eventually I would move the potty further away and further away...Finally it was permanently in the main the bathroom. Hang in there! smile
