Mom's lullaby always good, even if off-key

New research has suggested that babies do not care what their mothers sing or how bad their voices are, as long as they perform it with soul.

Alison Liew Creighton, a PhD student at the University of Western Sydney's Baby Lab research centre, has researched on how the mother-baby relationship gets influenced by lullabies.

"We already know that singing in the first year of life builds the mother-infant bond, which is the foundation to a child's development," the Sydney Morning Herald quoted her as saying.

Creighton's research looks into how play songs and lullabies help mothers and babies develop a bond by measuring their heart rates and observing their behaviour.

"It doesn't matter if you're out of tune; what's more important is that mums sing in a manner that captures their infant's attention and engages them," Creighton said.
