How do i celebrate christmas with my 5month old?

My son will be 5months old right before Christmas eve. I don't know how to celebrate Christmas with him. I am a huge fan of Christmas, and I want to decorate, and do fun activities, but not sure how to make it where its safe and fun for my son. he will be 5months old so any ideas, or advice for activities decorations, gifts for my son? I want his first Christmas to be something I can show him when he gets older.

    We had my daughter unwrap some gifts with our hands in hers it was funny, also sing songs, play with a new toy, read christmas stories. Take lots of pic, our little one was dressed in a few outfits.
