Good Morning Britain viewers were left in tears as the parents of two-year-old Leni Forrester made an emotional plea for help in a race against time to save their daughter.
Appearing on Tuesdayâs (March 24) episode, Leniâs parents, Gus and Emily, spoke to hosts Susanna Reid and Ed Balls about her devastating diagnosis.

Parents of young girl with childhood dementia appear on Good Morning Britain
Susanna explained the urgency of the situation, telling viewers the family are âin a race against time to protect their daughterâs lifeâ.
Leni has Sanfilippo syndrome, a rare genetic condition often referred to as childhood dementia. This means she will begin to lose her memory and motor skills from as young as three.
âThe effects are irreversible,â Ed added. âThereâs currently no cure.â
Emily described her daughter as âsunshineâ, but heartbreakingly revealed the condition often shows no early signs.
âThe most shocking part⊠is that we didnât notice anything was wrong,â she explained. The diagnosis only came after genetic testing within the family.
She continued: âThey donât really show any symptoms until they turn two. Then itâs a very rapid decline.â
Fighting back tears, Emily admitted: âThe future is very, very dark for children with Sanfilippo.â
She explained that Leni is expected to lose cognitive and motor function before tragically passing away in her early to mid-teens.

âThis is one of the saddest things Iâve ever heardâ
Despite the bleak prognosis, there is hope.
Gus revealed there are potential treatments, including enzyme therapy and gene replacement. However, access is limited, with trials currently taking place in the US.
Emily stressed the urgency, explaining Leni must receive treatment within the next year to have a chance at a normal life. Gus and Emily are urging for government support to fund treatment before itâs too late.
During the segment, little Leni briefly appeared on screen, toddling onto the set before settling with her parents, a moment that left viewers especially emotional.
Afterwards, many took to social media to share their heartbreak.
One wrote: âThis is one of the saddest things Iâve ever heard. Such lovely parents. That poor little girl. No wonder they were in denial.â
âThis is so heartbreaking. I hope and pray Leni gets the help she needs,â another added.
âSo sad. Bless her,â a third agreed.

Leni meets Jesy Nelson
Leniâs story has already touched many, including Jesy Nelson, who met the toddler earlier this week.
In an interview with The Mirror, Jesy described the meeting as âincredibly emotionalâ.
âChildren like Leni deserve every chance at life,â she added.
Emily also praised the singer, calling her âsuper inspirationalâ and âa really genuine, lovely personâ.
Jesy has been working to raise awareness for rare conditions after her twins were diagnosed with Spinal Muscular Atrophy (SMA).
