This is a heartfelt ballad that Sir Mix-a-Lot wrote for his newborn son. It was meant to be a song of promise where he vows to always protect his child and stand between him and danger. Originally titled "Baby Get Back". Sadly he couldn't read the song title or lyrics he had written down on the napkin and instead it became a song about booty.
I can only think of one song that says “baby “and is about an actual baby...It’s not one of my favourites, I don’t even like it, but I like music questions so I’m answering it.
