Won't take a binky if Im around

So a couple of weeks ago I mentioned to Andrew that Jack won't take a binky. Andrew replies that he will, but you have to hold it in his mouth for him. I assured him that I tried and it didnt work- he just spits it out. So the other day, I come home from work and Andrew says, "Look hes taking a binky." As soon as Jack realizes that Im home he wouldnt take it. He spit it out and wouldnt let it back in his mouth. He obviously wanted something else. Oh that kid...at least he takes a bottle.
