HALLOWEEN COSTUMES

I have a 2 year old son and an 8 month old baby daughter. For my sons' first Halloween the whole family dressed up together as a "theme" you could say. My husband was Popeye, I was Olive Oil, and my son was Sweet Pea. This year I want to dress my kids in a " theme" or in someway where their costumes work together. Below are some picture combo ideas I collected from Pinterest. I'm just glad they are too young to decide what they want to be for Halloween. I'm going to have fun dressing them up while it lasts. What do you think? Which theme do you like?
