DS 5 with CP -any ideas on how to help him stand and do wee wees!!

[baseW]

Hi,
my DS5 has CP therefore giving him problems with balance and coordination.
He wears a tight lycra suit - shorts and top and it is giving him nothing but grief going to the toilet as he prefers to sit.
He has tried before several times but he doesnt seem to be able to grasp (literally!!!) how and where to point it and where it is going to land!!
Any ideas would be a great help - not bothered about sprinkles - that's what Mr Muscle's for
Thank you

You can get little stickers to put in the toilet, or a floating ball with face on.
