kid stuff

Nothing to it

Kid stuff refers to things suitable for or associated with children—toys, games, simple entertainment.

By extension, it dismisses something as too easy or unsophisticated for adults: Calculus? That's kid stuff compared to real analysis.

The phrase often carries condescension, implying the subject lacks seriousness or challenge.
