I wouldn't stop. It is important (even with bottle feeding) to switch sides. To activate different sides of their brain. Right now I am nursing dd on my left side rubbing the left side of her body. Next feeding we switch.
If i were you and were block feeding-
i would offer the right side 1st each time. And I would finish with the left and then pump the right side.
Once I noticed it starting to catch up in production I would only feed one side per feeding
