Exposing Adventism - Children resurrected with wings?

SDA prophetess, Ellen White, assures us:

As the little infants come forth immortal from their dusty beds, they immediately wing their way to their mother's arms. They meet again never more to part. But many of the little ones have no mother there. We listen in vain for the rapturous song of triumph from the mother. The angels receive the motherless infants and conduct them to the tree of life. Jesus places the golden ring of light, the crown upon their little heads. God grant that the dear mother of "Eva" may be there, that her little wings may be folded upon the glad bosom of her mother. (The Youth’s Instructor April 1, 1858)

We passed through the wood, for we were on our way to Mount Zion, as we were traveling along we met a company who were also gazing at the glories of the place: I noticed red as a border on their garments. Their crowns were brilliant--their robes were pure white. As we greeted them, I asked Jesus who they were? He said they were martyrs that had been slain for him. With them was an innumerable company of little ones, they had a hem of red on their garments also. Mount Zion was just before us, and on the Mount sat a glorious temple, and about it were seven other mountains, on which grew roses and lilies, and I saw the little ones climb, or if they chose use their little wings and fly to the top of the mountains, and pluck the never fading flowers. (The Day-Star January 24, 1846, Early Writings, pg.18, Spiritual Gifts Volume II, p.54)

How fascinating. Christ did not have wings on his resurrected body, and we are to have a body like his. The addition of wings would make us a new species.

Did these resurrected children not grow for a thousand years? Why are they still children in the new earth - with red borders on their garments showing that they were martyred? Other passages state that minor children are "covered" by the faith of believing parents (See "Last Day Events" p. 293). Why then would the infant child of an unbeliever be saved?
