The young boy hurled from the Tate Modern viewing platform more than a year ago has started to walk with the help of a cane and assistance with his balance.
An update from his family revealed the seven-year-old has had his medication lowered, is feeling less pain and is trying to sing.
The child was thrown from height at the London art gallery in August last year by teenager Jonty Bravery, who is now serving a 15-year prison sentence for attempted murder.
Since then, the young boy has been recovering from life-changing injuries in his native France, with his family posting regular updates.
The latest said the boy is no longer allowed to go home on weekends, so his family members are having to spend seven days a week in hospital.
They described this as “very tiring because of the noise, and also very disturbing”.
“Our son’s memory is once again greatly affected. He no longer remembers what he did that day or what day it is,” they said.
But they added he has been making improvements in other areas and is now “able to walk with a tetrapod cane while we hold him by the back of the coat for balance”.
It followed an announcement in September that he was able to stand unaided.
“He also has less pain, so the doctors were able to lower his medication. He tries to do more and more things with his left arm like holding his tube of toothpaste or his glasses case to close it,” they said.
“He continues to recover his breath. He still speaks very slowly, but now speaks word by word and no longer syllable by syllable.
“He tries to sing and make up songs with rhymes. He was able to start using the blowpipe with the rehabilitators to continue improving his breathing.”
The boy’s family added they are “impatiently waiting” the return of weekend home visits because he misses his grandparents and friends.
