Similac moms... poop question lol TMI

Se

So I recently switched my lo from earths best to Similac, due to her having occasional formed stools which her pedi said was not optimal. Her poop now is more glossy though, almost mucousy. I know that Similac uses a different oil blend than most formulas out there (no palm oil which can harden stools) so I wonder if this is why. Any moms using Similac could you please tell me if this is what your lo poop looks like too?

Thanks
