Why did Karin keep the umbilical cord, if she's not Sarada's mother?


I'm just very confused about this situation.Why did Karin keep the umbilical
cord, if she's not Sarada's mother?Anyone explain it.




Karin kept the umbilical cord as a memento of her help during Sarada's birth.
Canonically being the one who offered assistance to Sakura while Sakura was in
labor and the one who contributed to Sarada's delivery, Karin was very helpful
to the Uchiha family back then. Through her actions, she formed a bond with
them, and the umbilical cord basically serves as a reminder of that exact
connection.

**By the way, Sarada's parentage indeed isn't debatable anymore.**

Her true parentage was already officially confirmed, and this happened for the
first time all the way back in 2015 in the manga called _" Naruto Gaiden: The
Seventh Hokage and the Scarlet Spring"_. Following this, the confirmations
from the manga were animated in the anime _" Boruto: Naruto Next
Generations"_, and after this they were even strengthened in many other
episodes.

Below, there are all the canon panels/moments that serve as confirmations
about Sarada's real parentage.

**The confirmations offered by Sakura:**

  * In the manga ( _" Naruto Gaiden: The Seventh Hokage and the Scarlet Spring"_, chapter 10):

So, everyone needs to learn the **difference** between the aspects of a story
that can be theorized on and the ones that straightforwardly can't. **When
something has already been canonically established, there is absolutely no
point in making any new _theories_ about that very same fact since it simply
can't be altered.**

**Sakura was established as the canon biological mother of Sarada, and that's
the end of the matter.**
