When Kimberley van der Velde’s fourth child was just a few months old, she could tell that he was not developing like his older siblings. “As a mum, there was something in my gut so deep down and so strong telling me there is something seriously wrong with him,” she says. “He was a floppy baby, who couldn’t hold his head up, he didn’t move his legs, they were frog-shaped and bent inwards.” She was right. Her son Rocco was diagnosed with Spinal Muscular Atrophy Type 1 when he was four months old.

SMA is a progressive muscle-wasting condition and is the most common genetic cause of infant death. It has made national headlines recently, after a series of candid interviews from former Little Mix star Jesy Nelson, whose twin daughters have both recently been diagnosed with the condition – after “the most gruelling three, four months, and endless appointments”, she says in a video posted to her Instagram.

Similarly, Rocco’s diagnosis was far from straightforward. Despite how early Kimberley spotted symptoms, medical professionals were slow to take her seriously. “I took him to my GP – they said he was a lazy boy who will catch up,” Kimberley tells the JC. “I was completely dismissed to the point that I started to question my own sanity.”

This is especially frustrating for families affected by SMA because the earlier the condition is identified, the more effective all three of the main SMA treatments are – including Spinraza, the drug that Rocco takes, and Zolgensma, which Nelson’s twins have started on. According to SMA UK, “once symptoms appear, motor neuron damage has already occurred and cannot be reversed”, and that irreversible damage only escalates the longer it is left untreated.
