Can my 3 month old baby see ghosts?

I dont see why not. If they worry you then put a religious item in the babys room such as a cross if you are christian. If a dog or cat stares at the same thing as your child then I would bet that is what he is seeing. I have exorcised many homes of spirits and most of them were the noisy variety. I have never encountered one that was dangerous. I did have one shut lights off on me in the bathroom during a shower and then steal the towel. I was the only one home at the time. That is the worst it ever got.
