Potty or real toilet?

sometimes she will poop in the regular toilet sometimes in the diaper. I wonder if putting a little potty will help or make it worst since she has already used the regular toilet?

    We have a little ring that goes on the regular toilet that Tristen uses. I think his is ninja turtles. It doesn't sit up real high and he was too big for the normal potty chairs. Ours has a clip that it hangs on the side of the toilet on so that it is easy reach for him to get and put on the toilet when he needs it.
