Essays / Christmas essays - Writing about a childhood Christmas; 2-3 page narrative paper [13]

I am having a really hard time with writers block. I need to write a 2-3 page narrative paper. I can sum up my story, but I am having a hard time figuring out how to describe what I am writing. I am writing about a childhood Christmas. I wake up in the morning and see that Santa Claus has been to my house. I got a Cabbage Patch doll, and from there I don't know what to say. I have about 1 page so far and now I'm stuck.
