I would do it but I have to add, someone MIGHT ask. We went during my son's actual birthday week and the CM who gave him the button at check in said to wear it all week so he did. He got TONS Of birthday wishes. A lot asked him how old he was. The thing is, my son is a literal kind of dude so instead of just saying "11" he'd answer well I'm actually still ten but my birthday is... You get the idea. The problem occurred two days before his actual birthday when we went to Monsters Inc Laugh Floor. Yeah, guess who got chosen to talk. And when the monster asked his age, he did his regular, actually today's not my birthday. The monster's jaw dropped. Camera pans over to the seat next to him which, THANK GOD, it just so happened my Mom sat next to him and not me and Monster says "Somebody wanted some free birthday cake." It. Was. Hilarious. After that Ds got a chance to say that his birthday was in two days and that he would be 11. And all was well. Probably one of the the best and most embarrassing Disney moments simultaneously.
