I dunno, I saw that Kishi comment too, you don't neccessarily need to be "blood" related to be considered a Mother to a child.

I can see something like, Sasuke and his group were looking for Oro, Karin got killed and Sasuke took her to Sakura to raise. But so she isn't raised in ridicule (as you know how cruel kids can be, look at Naruto's own childhood) he married Sakura and Sakura is a nice enough person to raise someone elses kid, especially if that child was Sasukes.

If there was a true marriage between the two, Sakura and Sasuke, you would think there would at least be one photo of the event. Maybe even the whole old generation knows, like how most knew that the 4th was Narutos father but no one ever said anything. The fact that Sakura created all those fake photos...screams that shes not the mother IMO.
