Is there ever another reason other than you know what?
If it was worms, would he not be itchy all the time, or at least every night?
And how can the cycle continue when he never actually scratches his bottom with his fingers? (this is banned in our household and he is extremely good about not doing it. He has a nappy on at night) I thought they had to scratch to get the eggs under their nails, to get them back into the stomach to start the next stage?
And would dp and me not notice if we had them too?
