Reply to comment by Ansuz07 in ELI5: how identical are identical twins? Is it just visual? Is it DNA? Is it fingerprints? Do their naughty bits taste the same? how identical is identical? by SaltyMcLovin
So, are there parents on identical twins out there?
Is it obvious how to tell the two babies apart? Are birthmarks in different places easily visible?
I mean infants don’t do much for the first few months so I can imagine a case where they don’t bother trying to figure out which is which for a while. But I never hear a story like that. Parents are absolutely certain which kid came out first. How do they do it?
