We perform discrete-mode calculations for a parametric amplifier with a quantum pump and discuss some of the limitations on calculations of this sort in quantum optics. We calculate corrections to the squeezing due to pump quantum fluctuations to order N^-2, for a pump initially in a coherent state with average photon number N{}. We find that the limit to the variance of the squeezed quadrature due to the quantum nature of the pump goes as N^-1/2. .AE
