thanks Krissy. I do have one friend who used it for their son, and they said it worked well, but I think he was a bit older and already pretty much trained, but it was used just to teach him to stand & wee.

Right now he climbs up onto the loo. We have a step & seat thing that we use. But it takes him so long to climb up and turn around that it's not really that great for teaching him to get himself up on the loo, and in time! Which is why I wondered if the novelty of being able to run up to the loo and stand there and wee might work.
