The whole of my son's year group and the year below have been sent home from school thus morning as they have been decimated by D&V. Only 19 out of 34 in my son's class made it in this morning and another one was sick on the way home.
I know it can be hard to figure out arrangements if your child needs to stay home, and symptoms came come on quickly, but please, if your child shows signs of being ill, keep them at home! Schools have 48 hour policies to avoid this sort of thing happening.
