We demonstrate, in particular, that despite the consequent large amplitude oscillations of the eta slow-roll parameter, their effect is, on average, sufficiently suppressed to allow for a slow-roll trajectory. In addition, we demonstrate that, even though this also induces a parametric resonance that amplifies inflaton perturbations, this has a negligible effect on CMB scales in the relevant parametric range. Hence, the \u201cWarm Little Inflaton\u201d scenario can be realized with one less fermionic degree of freedom and no need of imposing an additional discrete interchange symmetry."
