Why do babies cry so much?

Calming a crying baby can be a difficult task for parents. The challenge becomes even greater when a baby starts crying during a car journey.

Parents often try different tricks such as shaking keys or making funny sounds but these methods do not always work.

To help solve this problem experts developed a special song called The Happy Song. It was designed to make babies feel happy and help parents manage stressful moments.

According to a report published by CNN, the song was created 10 years ago with the help of scientific research.  It was a joint project involving two psychologists and Grammy-winning musician Imogen Heap.

The song has become extremely popular over the years. It has been played more than 470 million times on Spotify. Many parents say it has made car journeys and daily life at home easier by helping calm their crying babies.

As the song marks its 10th anniversary the research behind its creation and its worldwide success have attracted renewed attention.

How was The Happy Song created?

The Happy Song was developed in 2016 at the request of Cow & Gate, a British baby food company.  The company wanted a song that could make babies happy and give parents some relief during difficult moments.

To develop the song, music psychology expert Lauren Stewart and child development specialist Caspar Addyman worked with Imogen Heap.

At the time Heap’s daughter was around 18 months old, which also gave the musician personal experience of understanding a young child’s behaviour and interests.

The team collected information from more than 2,000 parents to discover which sounds attracted babies’ attention.

The findings showed that babies responded particularly well to sounds such as animal noises and other babies laughing.  These sounds were later included in the song to make it more interesting for young listeners.

Researchers tested different tunes on babies

After developing the musical ideas, the researchers tested them directly on babies. Imogen Heap created four different tunes, which were played at different speeds to 26 babies aged between six and 12 months.

The experts carefully observed the babies’ movements facial expressions and sounds to understand which tune they preferred.

According to the research around 80 per cent of the babies responded positively to the tune that eventually became The Happy Song.

The team also tested different musical speeds. Initially they thought babies might prefer faster music because their heart rates are generally higher than those of adults. However the experiments showed that babies preferred a relatively slower tune.

This finding suggested that making babies happy through music is not simply about playing fast songs. The melody sounds and overall style of the music also matter.

Why does the song attract babies’ attention?

One important feature of The Happy Song is the way the singer uses her voice.

The song follows a style known as motherese, which refers to the natural way adults often speak to babies.  This usually involves a higher pitched gentle and cheerful voice with clear and expressive sounds.

According to Caspar Addyman, this style helps babies recognise when someone is speaking directly to them. The song also includes simple words and sounds that young children can hear and respond to more easily.

By combining music, familiar sounds and child friendly language the team aimed to create a tune suited to babies’ developmental stage.

Imogen heap’s daughter helped inspire the song

Heap’s daughter, Scout also played an important role in the song’s creation. The idea for its main melody came from listening to Scout humming.

The lyrics were also inspired by her interests, particularly her fascination with different forms of transport.

The song mentions bicycles, submarines, helicopters, trains, aeroplanes and rockets travelling towards the stars.

Even the laughter heard at the beginning of the song belongs to Scout. Having her daughter nearby during the recording helped Heap maintain a natural and cheerful style that would appeal to young children.

Heap also wanted to make sure the song would not become irritating for parents even after they had listened to it many times.

Why has The Happy Song become so popular?

Child development expert Caspar Addyman believes the song’s success may partly come from the way it treats babies. Rather than using sounds that seem to suggest babies cannot understand anything the song communicates with them in an engaging and respectful way.

Over the past decade The Happy Song has gained popularity among parents around the world.

It has received more than 470 million plays on Spotify. A 10 hour version of the song on YouTube has also been viewed more than 14 million times. Heap said she did not spend much time promoting the song. Instead parents shared it with one another helping it reach more families and new generations of parents.

The musician explained that her goal was never to make a large amount of money from children around the world. She simply wanted to create something that could bring a little peace to families during stressful situations such as traffic jams or difficult journeys.

A Song That Brought Relief to a Worried Father

Heap also shared a personal experience that showed how the song could help in a stressful moment. During a flight she noticed a father struggling because his baby would not stop crying. She offered to play The Happy Song for him.

According to Heap the baby’s behaviour changed as soon as the laughter at the beginning of the song was heard.

The father was so grateful that tears came to his eyes. The experience highlighted why Heap had wanted to create the song in the first place: to offer parents a simple way to make difficult moments a little easier.

Final thoughts

The Happy Song shows how music can be designed around children’s interests and developmental needs. By using cheerful sounds gentle rhythms and simple words its creators aimed to capture babies attention and help them feel more settled.

Although babies may respond differently, the song has become a useful option for many families. Its success also shows how scientific research and creativity can work together to support parents during everyday challenges.
