I have two boys. One sat down to potty train. I had the same problems with between the seat\base. My youngest likes to stand up. We used a stool for him to stand on and small paper stars that he could throw in the water and aim for. make it fun, it always works. There are specialty toilet papers that work also. Throw a designed square in and aim. Great target practice. Good luck!
