The devoted wife also paid tribute to her beloved husband Chris Hughes for staying strong when she ‘fell apart’ after suffering the colossal loss of her life.
Lifting the lid on the meaning of the precious song, Amanda told Mail Online, “The closing lines of this song are ‘You took my life with you, took my world with you’ and so it’s for Theo, our baby who was born sleeping and for Chris who stayed strong when I collapsed.
“It was Chris who told me that he was still thinking of Theo when he heard that song that overwhelmed me, so it’s his song for Theo too.
In 2011, Amanda was seven months pregnant with her son Theo when a scan revealed her heart had stopped.
The Britain’s Got Talent star then underwent a Caesarean section to deliver her ‘sleeping baby’.
Amanda shared the heartbreaking details of how she found out her baby had died on BBC One Dear NHS Superhero’s poignant show earlier this year.
“I held him in my arms for the first time and that’s when I realized I was still a mom even though he was sleeping soundly.
She described her beautiful baby as having perfectly shaped eyebrows “like all of her children.”
“What I remember the most about her are her perfectly shaped eyebrows. My husband says our children inherited them from him, ”she laughed.
The TV star insisted she couldn’t have gotten through the devastating ordeal without the help of the incredible NHS staff.
