Many Catholics are not aware of the fact that the song “Mary Did You Know”, is heretical.
“Mary Did You Know” is a very popular song with many Catholics. Many, however, are not aware that the song in heretical and should not be performed in Catholic venues. Below is a critique of this song by two orthodox priests.

Your suspicions regarding "Mary, Did You Know?" are correct. The very title of the song is misleading. We need to remember some of the effects of Mary's Immaculate Conception. One effect was that she received the same gifts that Adam and Eve had before the Fall. One set of gifts Adam and Eve had are the preternatural gifts, of which there were 3 kinds. The one of most interest to this discussion is infused knowledge. Infused knowledge is a special knowledge of the providence of God. It is the ability to see in the natural the supernatural of what God is doing. Mary saw the supernatural ramifications of all that Jesus said and did. Recall that Luke tells us that Mary "pondered all these things in her heart."
Also, Mary was "full of grace" from the moment of her conception. Her will was completely united to the will of God at all times. She experienced throughout her life the "transforming union", the pinnacle of the spiritual life possible here one earth. Souls in that state of union have a much greater knowledge and love of God, the spiritual writers teach us. Plus, Mary knew the Hebrew Scriptures intimately. So she knew that Jesus was the Incarnate Word of God (Lk. 1) as well as the Suffering Servant of Yahweh (Is 52-53). She also knew from Simeon's words that she would suffer with Him. Conclusion: she knew a lot more than is implied by the song "Mary, Did You Know?". Please do not include that song in your repertoire. Hope all this helps.

You hit the nail on the head re: the lyrics of the song. My concerns are the same as yours. The song is an appeal to the mystery surrounding the Incarnation and Nativity. That's fine, as far as it goes. The lyrics, however, leave the door open to erroneous and heretical opinions, thanks to their ambiguity. I would avoid performing or promoting the song for that reason.
