There will come a point and time when you've got to train your little boy to go to the toilet without your helping hand, but what happens when you head out in to the big wide world of motorway service stations or pubs?

Those crazy white urinal things on the wall must really confuse the little ones. So what do you do? You invest in the world's only flushable toddler urinal of course.

The plastic urinal can be stuck to the wall or positioned on its included feet and comes with its own flush system to give it that truly authentic feel - although we don't fancy having to empty the draw out at the bottom afterwards.

However with phrases like "Little girls need to sit, but with the new Peter Potty, little boys can stand like Daddy" and include benefits such as "Sized to fit and grow with your little boy" you know there isn't something completely right about this invention.

Costing $50 and winner of an iParenting Media Award, the Peter Potty is available from a number of retailers in the US, some of which will deliver to the UK.

However purists will be disappointed to hear that you don't get those yellow piss cakes included in the box - you'll have to nick those yourself when you're next down the pub.
