We've taken DS (4) to the continence nurse/clinic but it was for constipation issues rather that wetting. Honestly, she was a wealth of information, unfortunately she didn't have anything to offer us that we hadn't already tried. That said, we are chronically constipated (medicated) and seeing a paediatrician for our issues. I think if we weren't so severe and long term than she probably would have been our answer. She was very understanding. Not sure that any of that helps, sorry.
