Climbing onto the loo - how to get up there?

[hovely]

In her latest quest for total independence dd has now started emptying her own potty into the loo and trying to clean up with toilet paper with disastrous consequences. So from now on I'd like her to use the toilet every time.
She's OK with it, and we have a padded training seat, but I don't know how to help her get up there. We've got a little plastic stool (the kind like an inverted box) but it just isn't high enough.
What have other children done? Anybody know of a safe 2-step stool?

How old is she ? Our dd was potty trained until we moved a few weeks ago and relapsed. We're getting back on track but she now definitely prefers the toilet. She's quite petite (only about 90cm tall) but can still get herself on quite happily with just a small Ikea step and no seat. She turns around and shuffles on backwards. You can buy all in one steps/overseat (Argos or Index I think) with handles to help them get up safely.

pity you didn;t live in the NE hovely as I have a two step loo seat going begging. DS2 doesn't use it

How about this one from the Great Little Trading Company - here ?

hovely - we've got a really sturdy two step toilet seat which works brilliantly, I got it because ds was having so many problems with the inverted box type thing. I think I got it in John Lewis - the label on the front says 'III rotho babydesign' - not sure whether that is three number ones at beginning or three letters.

sorry - of course it isn't a two step toilet SEAT - it's a two step plastic thing which is shaped to sit on front of the loo. Must preview..

I found the padded seat more trouble than it was worth - it kept slipping around as ds tried to manoeuvre himself onto it.
He gets on to the toilet much better without it - then he just hangs halfway down into the toilet

If you go to www.additionsdirect.co.uk and put in catalogue no. XJ5367 sorry couldn't work out how to do a link properly. This is a brilliant step/seat which we found really helpful.

We got this step from Lakeland. It's the perfect height for both the toilet and the basin. And because it folds flat we have even taken it away on holiday with us!

We tried several seat inserts, but returned all of them because they slipped about on our loo. In the end we got a Rymax Family Seat from John Lewis. The one seat insert that was any good was the Baby Bjorn one, but the shaping which kept ds feeling secure also made it almost impossible for him to climb up on his own, so we left that at my parents' house for when we visited.

thanks everybody. John lewis came up trumps, I had not thought of looking there.
