More importantly, I think you're both wrong. Clearly what this woman is seeking is another of some unknown item; the baby is obviously just there for emphasis, like "I'm going to the market, baby, do we need pistachios?" The lack of comma between "another baby" is probably because they're Swedish.
So having clearly established that she wants another of something, we need to determine what that is. My guess is the song is about a record deal; perhaps Ace of Base sensed their two-hit wonder status coming, and wrote a song pleading for another record before they're "gone tomorrow".
This is why I'm in med school and not law school.
PS Excellent use of DED Joseph
