In my preschool class I strive to teach truth to the children. During the holidays I may tell them stories of the historical St. Nicolas or St. Patrick, but I cannot find one for Easter. I usually just avoid the subject of magical rabbits and Easter eggs and tell my parents that they may explain those stories according to their own family traditions.
Interestingly (to me, at least), one of my 5 year old preschool students, whom after hearing the true story of Easter in class, informed his mother at home, "I do not believe there is a talking rabbit who goes around bringing eggs to us."
Kids DO get it, they want it....tell them the truth of the resurrection even with the gruesome details. The truth pricks their hearts. They know how important the truth is to us also. Do we model the truth for our children? Upon who do we place the most importance: the Reality and glory of the cross or on a talking rabbit who brings colored eggs? The children are watching and learning from our example.
