If you keep doing it for them, they’ll never learn it. Hand over the controller.

Doing it for someone is faster right now and expensive later. Every time you take the task back because it is quicker, you confirm that they cannot do it and remove the only way they would learn, and eventually the job is permanently yours. It feels like help and functions like a bottleneck. Watching someone be slow and slightly wrong is the actual cost of them getting good.

Hand it over and sit on your hands. Let them do it badly, ask what they would try next, and resist stepping in unless something real is at stake.
