Ghosts Appearing as Children [Latter-day Saint perspective]

> Elder Mark E. Petersen (1900–1984) of the Quorum of the Twelve Apostles explained that the physical body and our spirit are similar in appearance: “Every one of us is a spirit, and our spirit occupies a body of flesh and bone. The spirit is the real person. Our spirit resembles our body, or rather our body was ‘tailored’ to fit our spirit. The spirit bears the image and likeness of God, and the body, if normal, is in the image and likeness of the spirit” (The Way of the Master , 124; see also 1 Nephi 11:11). From this, the spirits of those who have dies _should_ look like the individual as they lived; however, it is also taught that our spirits were adults _before_ this life began. As I understand it, this earth is also the world which is inhabited by those who have died. Assuming that ghosts are those spirits of those who currently do not have a body (either due to death or as one of Satan's host), why would ghosts ever appear as children?
