Toilet training books where children go on the toilet, not the potty.

[Voidka]

Does anyone know of any?

I am going to try to toilet train DS(5) in the Easter holidays and have been looking but can only find potty ones.

There's this one, but it might be American in tone?

This one has potty in the title, but seems to be about toilets and has a flushing toilet noise (!)

No idea why this one is so expensive!
