The splash guard fell off into the toilet bowl on first use, so we now just leave it off as it is a bit of a nuisance and makes getting onto the toilet a bit tricky. Much better without it. The seat itself is nice and comfy and and seems a good fit on what is quite a large toilet seat. Seems to be quite steady, no falling off.

A few days later and success! FINALLY!!!!! First poo on the toilet.
Also used a netmums tip about getting them to blow up a balloon while sitting on the toilet. Uses the same muscles apparently.
Thanks AMAZON, a new toilet seat (cars), a few books on the subject of poo, a balloon, and the promise of a surprise (precious petzzz) if he goes has worked wonders where no amount of stickers, stars, bribes, and pleading have worked before.
RELIEF!!!
