But there's certainly also the possibility that the parent thinks he believes it, although all of his actions and other beliefs reveal that he doesn't believe it. Daniel Dennett has addressed this well. No one debates the existence of Mt. Everest, and nobody has to assert that they believe in it. To identify yourself as someone who believes in something, there must be some question as to whether or not you would. People who say they believe in something which is at the core of their group identity, and for which there is no strong evidence, are rather obviously choosing not to question those beliefs the way they would question any other belief -- including the very similar beliefs of other people's religions. So the fact that the parent "believes" in holy reincarnation or holy levitation or holy mindreading doesn't necessarily mean that he is being honest when he tries to raise his kid to believe in such things. Do they really believe those things to be real the same way they believe Mt. Everest to be real? If not -- if there is any hiccup to his belief -- then he is lying to his kid as well as himself.
