What to put in the Christmas Eve box?

My daughter will be 4 next month.. We like todo the Christmas eve box with things we can do and be used on Christmas eve. Usually its a movie, pjs and got chocolate with snacks. But this year we are making home made hot chocolate and snacks, already have pjs and tons of DVDs. But still wanting to do a small box for her to open. We will be super busy on Christmas so we will not have a lot of time for just our little family so I want Christmas eve to be our family day with just My husband and our girls (baby is 7 months) any ideas?
