The exaggerated singsong adults use with infants looks silly but may be doing serious work. These approaches differ on the mechanism and the proof: how parents adjust speech to a baby's feedback, which sounds hold infant attention, and whether the research leans too hard on narrow Western samples. Comparing them shows what we truly know about talking babies into language.
