When I was a small child, before the NHS got off the ground, it was quite normal for mothers to send their children round to play with a child who had one of the childhood diseases - german measles, chickenpox etc. Most of those illnesses were less severe in younger children than when they were older and it got them out of the way before school. That way also gave the child a natural immunity to the diseases without the putative risks, today, of innoculation.
Right, form an orderly queue and get your children round to Entwisi's. He can supply the jelly and ice cream.
