Life / Birthday traditions in Poland [30]

Because she feels like she's losing her culture... what Polish traditions or customs and decorations are there that I can incorporate into the party? I want her to feel "home" Are there special occasion drinks or food?? Should I decorate with the colors of the Polish Flag? Do I serve an actual birthday cake or is there another pastry that she would have eaten on her birthday/name day? Thank you for all of your answers :)

Merged: Polish Birthday Traditions & Ideas

I'm throwing my Aunt a birthday party next year and I would like it to be Polish themed. She has been in the United States for 8 years now and she feels like she's losing her culture. I want to surprise her by having many different Polish birthday traditions, decorations, and food & drinks. I have the food pretty much set, but I'm lost when it comes to the traditions and decorations. Thank you so much!!
