When I plug in my ds i have to wiggle around my cord until i find a sweet spot after finding the sweet spot my little light will come on like its charging but then it will shut off again and won't ch?

It sounds like you might be experiencing a problem with the charging port or the charging cable itself. The need to wiggle the cord suggests there could be a loose connection or damage in the cable or port. Try using a different charging cable to see if the issue persists. If it does, the charging port on your device might need cleaning or repair.
