It’s just really sad, unfortunately, it does come with these complications we had no idea about,” she added.Jesy Nelson speaks out to raise awareness after her twins’ SMA diagnosis:London Celebrity Sightings - JULY 13, 2015 - Source: GettyAccording to a report shared by Us Weekly on January 4, 2026, Jesy Nelson provided an emotional update on the health of her 8-month-old twin daughters.

They won’t reach the same milestones. Take them as they are,’” shared Nelson.“When the healthcare visit came, we were told, ‘They look great, they’re healthy and everything is fine, a few signs then started to show a bit later on that they were struggling to feed properly. It was getting gradually less and less and less,” she added.

It stands for spinal muscular atrophy, which can affect every muscle in the body down to legs, arms, breathing, swallowing and … over time it kills the muscles in the body, if it’s not treated in time, your baby’s life expectancy will not make it past the age of 2,” shared Jesy Nelson.Nelson continued to share the emotional bits of her story.“When [the doctors] assessed the girls, we were told they’re probably never going to be able to walk, they’ll probably never regain any strength, so they will be disabled. The best thing we can do right now is get them treatment and just hope for the best.”
