This is how to make your baby a genius

One of the most smile-inducing milestones in a baby’s life is when they manage their first word. But that magical moment could happen sooner, depending on the way parents or carers speak to the child.

Scientists have long suggested that babies prefer what’s called parentese – when mothers and fathers modulate their voice, including making it higher in pitch.

In this black-and-white video, seven-month-old Paul shows a distinct preference for this style of baby talk, by turning his head to the side where his mother is speaking parentese, instead of the side where she’s talking normally.

And research has found children of parents coached in speaking parentese start talking sooner and have a greater vocabulary than children whose parents had not received the same training.

What is parentese?

It’s tempting to coo or babble at your newborn – or even make up words like tootsies for toes – and abandon all grammar.

But numerous studies have shown true baby talk actually involves using proper grammatical structures, speaking about an octave higher than normal, saying things more slowly, exaggerating the rise and fall of your voice and, crucially, leaving pauses to give baby a chance to respond.

All of this serves to make you sound happy and encourages your baby to engage in communication, which is an important step in their cognitive and social development.

At 14 months, babies whose parents had been coached in parentese were producing significantly more words than babies in the control group, research by the University of Washington found. They were also babbling in more of the recordings made.

Brain-boosting

Reading and talking to children from birth is crucial to give them the best start in life and help them to be school-ready, says Professor Anne Fernald, a developmental psychologist at Stanford University.

In experiments that tested children’s language processing abilities, she has found children whose parents talked to them less could lag behind others by as much as six months by the age of two.

"Parents who talk more to their kids are more likely to realize their developmental potential," Prof Fernald says. "You are obligated to feed them, wash them, and clothe them. Talk to them while you are doing it."
