  We present preliminary measurements of the cross sections for e+e- --> KS KL
pi0 and KS KL pi0 pi0 obtained using the technique of Initial State Radiation
with 469 fb^-1 of e+e- collision data collected with the BABAR detector at or
near the Upsilon(4S) resonance. The resonant substructure of KS KL pi0 is
investigated, and branching fractions for the decays of the charmonium
resonances J/psi and psi(2S) into these final states are measured.
