A five-year-old Thornbury boy is taking on a walking challenge to raise money for a charity providing support for his deaf brother.

Alexander Walker, who is seven months old, is profoundly deaf and he and his family are being helped by the National Deaf Children’s Society.

Alexander’s brother Parker is now attempting to walk 100km during May to raise money for the charity, having already met his 50km target.

Speaking about Alexander, mum Olivia said: “We were told when he was eight weeks old he was profoundly deaf.

“My eldest has just started to understand what it’s all about.”

Speaking about the Deaf Children’s Society she added: “They provide pretty much everything when it comes to finding out your child is deaf, from sign language lessons to just having someone to talk to.

“They are just brilliant.”

Olivia and partner Lee have been accompanying Parker on his walks, helping him reach the initial 50km target after only half the allotted time had elapsed.

“He’s now going for 100k,” said Olivia.

“It seems like a lot but we have mapped out a lot of walks.

“He is tired. It’s getting him out which is good.

“We have found loads of different walks in Thornbury we didn’t realise were there.”

One challenge Parker wants to complete is to make it all the way across the Severn Bridge and back again.

So far just shy of £950 has been raised, far surpassing the initial target of £200.

“It’s gone so much better than we thought,” said Olivia.
