That’s a lie that Kakashi used to deliver Naruto groceries and stuff. Per canon, by the time Kakashi became Naruto’s sensei, Hiruzen took Kakashi to all of his future students’ homes and Kakashi was surprised by the expired milk and the state of the stuff in Naruto’s home. It was pretty clear he had never been in Naruto’s home. Plus, it was pretty obvious he had avoided Naruto for years out of guilt because he reminded him of Minato, his sensei who died. The only person who ever dropped things off for Naruto was the Hokage and Jiraiya. Jiraiya left that frog wallet once. I can’t think of anything else he did for Naruto before beginning to train him.
