I and my immediate family are Agnostic, so the religious side of the holiday holds very little meaning for us.
We dye eggs with the kids, and they each get an smallish Easter basket filled with candy and goodies on Easter morning.
This year, we are going out to brunch with some family Easter morning, then meeting up with DH's family in the afternoon. His sister is hosting a gathering at her house - egg hunts for all the kids, finger foods and socializing for the adults.
I have tried to teach my kids about the Rebirth symbolized by the Easter holiday. They have Christain family, and they have been taught the story of the resurrection. They have also learned about the Jewish story of Passover and the reasons for the observation of Lent. They have also been taught to look upon the turning of the seasons, the rebirth of the green grass and the flowers and the baby animals, as a chance for rebirth and new beginnings in their own lives. We talk about other spring holidays in other cultures, as well as the ancient pagan/Celtic holidays, and how many of today's holidays are based on them.
I want my kids to have all the information they can possibly have about just about everything.
A "big deal" though? No. No new dresses, no huge meals, no church services. Some fun eggs, a little candy, and some time with family, that's all.
