You just reminded me that my step-dad’s niece (my step-first cousin?) has identical triplet girls. They must be over ten years old now but I only saw them once when they were a few months old. The parents painted their toe nails different colors to help tell them apart. At the time the Mom could actually tell them apart from their cries but not Dad.
I’ll see your four and raise you one: the Dionne quintuplets. What is it with Canada and multiple births, anyway?
