I am aware. It is not contradictory for Jesus to put His nature in Himself while being born as a human.
It actually is, since it diminishes the fact that he is truly and fully God. His humanity is not merely an insertion into his divinity, but he became as fully human in every way as he was fully divine in every way. He wasn't God with a human skin or a human that had God inserted into him, or some other kind of admixture, but was from his conception fully human and fully God.
