So said DS2 (7) earlier. I didn't witness the poo or the "grains of rice", but I wouldn't be surprised - his nails are usually filthy, despite repeated requests for him to scrub them. Are we talking threadworms? How can we check for them, apart from checking today's poo? And if it is threadworms, do we need to see the GP or can you buy the medicine over the counter? And is it one of those scorched earth things where we have to burn all the soft furnishings, medicate the whole family and dress in shrouds for a fortnight?
(I've tried googling for images, but it just pulls up all sorts of horrifying images which I will definitely not be showing DS2 any time soon. He's already howling at the thought of having worms.)
