Jesy Nelson marks a milestone for one of her twin daughters after the child’s diagnosis of spinal muscular atrophy (SMA). Multiple outlets report that Nelson shared an image showing the daughter sitting upright in her wheelchair, describing it as a major step forward in her SMA journey. The posts are presented as part of the family’s ongoing experience managing the rare muscle-wasting condition.

One report also references broader public discussion around SMA testing and says Nelson was left “heartbroken” and “outraged” following that debate, though the core update across the sources is the child’s progress. While the outlets vary slightly in wording—describing the moment as a “huge milestone”—they consistently frame the development as a positive change for the twin’s mobility and day-to-day functioning.

Overall, the articles focus on Nelson’s social media update documenting the daughter’s ability to sit upright and the significance of that progression in the context of SMA.
