While we perhaps inculcate a bit more compliance than is strictly necessary, you can't make children not gullible. To be not gullible irreducibly requires enough experience with what is normal to know when something is not normal, and alas, not only do children have a straight-up calendar disadvantage there, the children that we are talking about are also more likely to not have a normal to compare against in the first place.
This is the wrong time to play that tune.
