haha thats hillarious. Your son is so cute. My daughter still has the look of true belief too. I think I know what you are describing. My son hardly sleeps and it took 4 nights before we could put a loonie under his pillow cause I couldn't stay awake late enough. My husband ended up placing it there at 5am when he got up for work
My kids still visited Santa this year for a picture at the mall. They know that isn't Santa but they still love the spirit of it
