The young boy who was thrown from the viewing platform at London's Tate Modern museum in August 2019 can now stand unaided.
The boy, who was aged 6 at the time, was thrown from the building's 10th floor by stranger Jonty Bravery.
He landed five floors down on an adjacent rooftop and suffered severe injuries including a bleed to the brain, fractures to his spine, and broken legs and arms.
Bravery, 18, is on the autism spectrum and has obsessive-compulsive disorder, BBC News reported. He said he threw the boy because he wanted to be on the news.
Bravery was sentenced to 15 years imprisonment for attempted murder.
On Monday, the family published an update to their Givealittle fundraising page saying the boy is "making good progress" after transferring to a new hospital/rehabilitation centre better suited to his needs.
"He can at last stand on his legs without any help or support!" they said.
"Furthermore, his memory is gradually improving: he can now remember activities he has done the same day or the day before!
"Regarding food, he now eats almost alone (after everything has been cut out and prepared for him) and, in a suitable glass, he begins to drink slightly thickened liquids!"
The family said the boy has also been able to try new activities such as adapted sports and equine-assisted therapy.
"All these changes have cheered our son (and us too) up and we are already seeing new progress."
They said the COVID-19 lockdown has been "really, really hard" as it has isolated the family, but they believe in the new centre.
The Givealittle page for the boy has already raised over €285,000 (NZ$507,294).
