I have lost count of the number of times ds (6)(and me ) have caught worms.
Obviously he's at school, and I work in the same school and everytime he gets it, I do, and vice versa. No one else in our family seems to suffer.
My cleaner I dust weekly, and hoover. He's a finger chewer (I have my moments).
But I can't help thinking some child at school is rife with them and keeps spreading them.
