Sounds like a lot of panic for 3 days of problem? You seem to have identified the issue, the kitten was fed food he wasn't used to by your dad while you were away?
yes, put back in bathroom. Put onto raw diet only (as meat only is blander and easier on stomach than kibble) and give his poor immature system a few days to recover from the upset.
And make sure you let the breeder know of the issue so that they can add their advice!
