we are on day 3 of keeping rhys' nappy off in the morning my question is about his potty. rhys seems to find it uncomfortable to sit on his potty because it is plastic and not padded. he prefers to sit on the big toilet upstairs (i have to hold his middle or he'd fall in!) what do you all think about those seats that can go on top of the normal toilet? im sure ive seen padded ones??
