13. Not a parent of twins, but am an identical twin. Our parents used to write A and B on the bottom of our feet with a sharpie to tell us apart until we got old enough to walk, then switched to color-coding our clothes (one of us wore pink the other blue). We were never mistakenly swapped though, I’ve always been a half-inch taller than my sister since the day we were born .(i’m the firstborn and thus baby A btw)
14. Once when we were toddling I ran into a table and got a black eye. Dad then told anyone who would listen that he would blacken my eye to tell us apart. Dad was kind of an asshole.
15. My SO has an identical twin. Their mother has confessed to them that she probably swapped them a few times when they were babies. Also, it’s impossible to know who’s who in baby/toddler pictures, because they wore identical clothes. Later it became easier, because they have different voices – one has a low and calming, the other a higher and more sharp sounding voice. I can tell them apart by their facial features, hairstyle, fashion sense, mannerisms etc.
