The effects of live parental infant-directed singing on infants, parents, and the parent-infant dyad: A systematic review of the literature.

Singing to infants is widely accepted as an enjoyable, positive, and beneficial interaction between the parent and infant across cultures. Whilst the literature suggests that live infant-directed singing impacts the infant, the parent doing the singing and the dyad in powerful ways, no systematic review of the evidence has yet been conducted. To this end, this systematic review identified 21 studies that investigated the effect of live parental infant-directed singing.
