When we lived a couple of hours away from my family & my ILs came over for breakfast (but we had no other big meal or celebration of the day), I made breakfast casserole & Jesus birthday cake.
Now that we live 15 minutes from my parents' house & go over there at 10 am to open presents (and eat cookies & Chex Mix until lunch at noon), I don't bother. My kids either have the candy from their stockings or store-bought chocolate donuts or both.
