Hymn Lyrics Search - Name That Hymn

I'm looking for the song lyrics from a Christmas Cantata that we sang in our Church choir about 30 years ago. I have it stuck in my head and would love to hear it again. It is a song that Mary sings to Baby Jesus right after his birth. I believe the name of it is "First Born". Some of the lyrics are: My first born, welcome to the earth. The Angels hover over head. Can't remember... So sleep, sleep little child. \
Would love to find this is anyone can help it would be a blessing.

Thank you!

The cantata was written by Joe E Parks "A Song Was Born". It's a lovely cantata. Our community came together to sing this.
