I haven't seen my grandchildren for over 2years, My grandchildren and I were very close, they are now 13, 10, 8 years of age. However in 5/2010 my daughter sd she no longer wants my craziness in her life. I have been involved a lot in her life and my grandchildrens life and now Im unable to see the children. What can I do to pursue my visits with my grandchildren? I miss them very much

Nothing. You don't really have rights as a grandparent to see them. If your daughter doesn't want you to see them, that's that.

May we ask what kind of "craziness" your daughter is talking about?
