Search for CP Violation in $D^{0}\to K_{S}^{0}\pi^{0}$, $D^{0}\to   \pi^{0}\pi^{0}$ and $D^{0}\to K_{S}^{0}K_{S}^{0}$
  We have searched for CP-violating asymmetries in neutral charm meson decays in 13.7 fb^-1 of e^+e^- collision data at sqrt{s} = 10.6 GeV with the CLEO detector. The measured asymmetries in the rate of D0 and D0bar decays to K0sPi0, Pi0Pi0 and K0sK0s final states are (+0.1 +- 1.3)%, (+0.1 +- 4.8)% and (-23 +- 19)%, respectively.
