Prime Video documentary Life After Little Mix gives a candid insight into Jesy’s pregnancy journey, and includes the emotional moment when she first learns her daughters have Twin-to-Twin Transfusion Syndrome.
It’s a rare and potentially life-threatening condition when twins share one placenta.
After undergoing an operation to treat the condition and a long period in hospital, the 34-year-old singer gave birth to her twins prematurely in May at 31 weeks.
A few months later, Jesy’s mother noticed the twins’ legs weren’t moving in the way she thought they should.
Following a series of urgent tests, they discovered Ocean and Story had Spinal Muscular Atrophy (SMA) Type 1, a severe and rare genetic condition that can cause muscle weakness and lead to death within two years if left untreated.
Jesy says she decided to let the cameras in so she could document “all these amazing memories” while pregnant and later show them to her children.
“Obviously it just did not play out in any way, shape or form in which I thought it was going to,” she says.
“But my reasons for making it before are now so different to what they are now.”
Jesy says she feels “so grateful” the cameras were there, and her new aim is to “raise as much awareness as possible” about the muscle condition.
She also wants to show her daughters “how resilient and strong and amazing” they are, she says.
