2nd Birthday

Luciana turned TWO on June 18th. Sadly, we really have not done a thing to acknowledge her birthday. We did take our trip, and that was lovely, but that was more an "Anniversary, End of School, Beginning of Summer, and OhYEAHLucyistwo" kind of all-in-one excuse to get away. Since then, a lot has happened, and here we are July. I sort of made piece with the idea that she is too little to really notice and decided to just let it be. It feels strange, but I was okay with it. Well, Sam was not... is not. He wants his baby sister to have a birthday party! It seems silly now, but I hear his point. What to do, what to do? Any thoughts out there of how to throw a "your big brother wants you to have a birthday party well after your birthday" party?
