There are identical twins out there whose parents confused one with the other and now they living their life with the name of the other sibling, never noticing because it doesn't make any difference.

What I’ve found is that after a week socializing with twins, it’s pretty much impossible to confuse one with the other, especially if they’re older. There’s always some little quirk that differentiates the two. The parents who raised them would have to be out of the world shitty if they can’t tell apart their children.
I could see this happening when they are babies though. Like 6 weeks in Bob becomes Tom and Tom becomes Bob and you might never know. I don’t think that would be harmful at such a young age though.
Yeah I can’t recognize my own daughter in the first few weeks/months of her life even if I look at the pictures and know its her.
Shit, I still can’t recognize your daughter.
That’s actually my childhood picture you’re holding. I would like that back please.
There was a case in my country where two babies were swapped at the hospital. One mom had the presence of mind to take pictures right after giving birth, which she used to prove that she was given the wrong baby (hers had a full head of hair). The other parents were blissfully ignorant of the fact there was a switch.
As long as they don’t have different allergies or had biometrics recorded and assigned to them at the hospital it arguably wouldn’t even matter.
And if one of them do have a bad allergy or disease you should really have a system in place to tell them apart and not rely on just looking at them and hope for the best.

Where I live, birth certificate registration require footprints taken by a nurse. I imagine identical twins still have different footprints pattern?

Imagine when you’re old and tried to compare your footprints out of curiosity only to find out your identity has been swapped this whole time.

Can confirm.

Yeah, there was an episode of full house with this idea - they used their footprints to tell them apart. I can imagine you couldn’t be doing that all the time tho.
Exact same plot in an episode of Suite Life of Zach and Cody
Having had twins, I can’t imagine it happening 6 weeks in for more than a few minutes. 6 hours, definitely. 6 days, maybe. But by 6 weeks, you know who is who. Even identical twins are pretty easy to tell apart after having spent significant time with them. It’s actually pretty common for parents of di/di identical twins (which are the type that could be fraternal) to not think their twins are identical only to have everyone else notice they are.
