We summarize our investigations of the second-order perturbations in loop
quantum cosmology (LQC). We shall discuss, primarily, two aspects. Firstly,
whether the second-order contributions arising from the cosmic bounce,
occurring at Planck scale, could be large enough to break the validity of
perturbation theory. Secondly, the implications of the upper bounds on
primordial non-Gaussianity, arrived at by the Planck collaboration, on the LQC
phenomenology.
