I have already got a childs toilet seat that fits ontop of the main toilet seat,it has handles too. and a plastic spongy seat.But I found it a pain because she kept asking to go for the sake of it and I was forever running up and down the stairs for her fake toilet.And I found it difficult because of leaving Kai alone too while I took her up to the toilet.
But luckily she sits on the potty downstairs,even though she doesnt do anything in it.But I will still try your idea of the stickers and she can stick them on the potty...so heres hoping
