Rayce Grieve’s new baby brother is not like his other siblings. Tripp was born with Down syndrome and was hospitalized for the first month of his life.

Rayce, six, has told his mother, Nicole Powell, 29, that he will always look out for his beloved brother – and has requested to embrace him one morning.

And when the student started singing ‘their song’ – 10,000 hours by Dan + Shay and Justin Bieber – the mother-of-five from Arkansas, United States, was overjoyed.

She captured the tender moment on her phone to share with her 39-year-old husband, JJ.

Nicola, a police officer, also shared it on Facebook, where it has received over eight million views.

‘It’s incredible,’ she said. I had been perplexed as to why we now have a baby with Down syndrome.

‘I believe it was to spread love and awareness.’ People are scared of what might occur.

‘However, he is flawless.’ It’s terrifying, but parenthood is terrifying in general. ‘I’m incredibly proud of my guys.’

During prenatal exams, Tripp’s parents learned he had the condition, in which one extra chromosome is present.

Nicole admits that she and her husband were ‘uninformed’ about Down syndrome and that doctors cautioned him about the possibility of major cardiac problems.

‘I was illiterate and uneducated,’ she said.

‘I reminded myself that I had four other children, all of whom adore each other; all I want is for them to love him as much as they love each other.’

‘We informed them right away. We explained to them that he would be different, but he would still be their brother.

“But we’re all different,” said the lads. And we told ourselves, “OK, this will be OK.”

Later scans confirmed his heart was healthy, and when she finally saw him after he was born by c-section, she thought he was “absolutely perfect.”

He returned home after a month in the hospital to his siblings Jayce, nine, Rayce, six, Grayce, two, and Reese, one.

The love ballad 10,000 Hours played on the radio on the way home in the car, and Rayce began singing it to his younger brother.

‘Both guys enjoy music,’ Nicole added.

‘Rayce was saying, “this song is about me and you” – he has no idea it’s about a husband and wife.

‘He decided it was their song,’ she says.
