Thanks for the reply good to hear it isn't unheard of. We had a small triumph today we went to the zoo, and I took the seat we use on the toilet at home with us, and she asked to go to toilet and actually used the toilets there with the seat (often she asks to go but won't use it when we get there when out) - will have to see whether can continue doing that, if so I will get one of those fold up seats to use.
