Did she just say that?

When we introduced the baby to our landlord yesterday, she was fawning over her and all of a sudden looked up and said to Gretchen, "she has an erotic mouth". Wait, what? I thought she must have meant something that was just lost in translation, but then I heard her say to her husband something about "ein erotischer Mund." I'm sorry, but is that a normal thing to say about a 5-day old baby?
