Hospital gives family wrong baby home, calls 10 days later to swap baby

A Twitter user made a tweet about how a family was called 10days after baby was delivered to tell them they took the wrong child home and demanding for a swap.

And then we wonder, what kind of mistake is this? How could they be so careless?

See screenshots of tweet below:

This guy just got a call from the hospital, 10 days after his child was born, that he went home with the wrong baby.

Hospital informed him to bring back the baby and swap. No big deal, it's just 10 days.

I am dead here ?????
