Leo and Paige only travel back once together and that is to see her parents death. However there were several times where Paige time-traveled back and met a younger Leo. For example she sneezed herself into a different dimension where she and her sisters had not met and she meets Leo there. She also travels back to meet a young Penny Haliwell via some go-go boots and Leo actually hits on her there.
