Same as your mother. She gave birth to Jesus who at that point was the incarnate, 2d person of the Trinity.
Of course Jesus was fully man, but He was also fully God.

Do you think Jesus was fully God when He walked on this earth, or do you think He was not?
Of course He was fully God. That does not make Mary the mother of His deity. Those who claim she is "mother of God" claim to know more about the mystery of the incarnation than is found in scripture.
