why don't you try putting her nappy on at night then popping her on the loo WHILE she is wearing the nappy? After a few days, take it off again, OR, try cutting the bottom out of it, so she still has the waistband on but nothing to catch the poo in - might help the transition? Also, what about a smaller potty - it's a better position for the bowels as the knees are higher. good luck
