A long time ago I used to think that the Jesus crucified on Good Friday and the baby Jesus at Christmas were 2 different people. and I didn't really know who this Jesus person was. I was wrong. I now know them to be one and the same person - Christ Jesus, Savior, King of kings and Lord of lords. So yes, Christmas and Resurrection Day are related, whereas the other holidays of the year don't really have too much to do with Jesus.
keep a journal of Christmas events. if you need a tree, you can get an aluminum one or buy one from a lot which has been expertly cut down, or if you have any experience, you can cut down your own. your child will probably
want a tree. don't disappoint them. even if it's a small one they can decorate themselves, which may be a real treat (and it fits in a car easily with the presents).
