A schoolgirl will brave the frosty weather in a charity walk to raise money for her little brother who has cerebral palsy.

Erin Walfisz, of Oakleigh Gardens, Whetstone, plans to walk ten miles from her home to Leicester Square this Sunday to help Max get the treatment he needs.

Max, seven, is unable to walk unless he is holding someones hand as the condition causes weaker muscles.

Money raised from Erin’s walk will go towards buying him a trike to give him more independence, and to pay for a revolutionary form of therapy which costs £1,500 per course.

After an appeal in the Times Series last month, donations have been flooding in and ten-year-old Erin has raised more than £6,000 for her brother.

The Woolfson Hillel, Southgate, pupil said: “I’m so excited for the walk and seeing how much money I manage to raise. I'm not nervous, I've been practicing.  "It’s nice that loads of people are sponsoring me. It’s going to be cold but I don’t care. I want to do this for my brother. I love him. I think he’s the best.”

Erin will be joined by family members and friends on the walk - including Max’s friend Casey-Beau Jackson, who has raised £1,500.

Max, who loves singing along to Taylor Swift and making up jokes, will also be joining his supporters for part of the walk in his chair.

Their mother, Dana Walfisz, said: “Erin knows what to expect now as she’s been training. I’m incredibly proud of her.

“Max knows what’s going on and he’s very grateful. People we don’t even know have donated - we want to say thank you to everyone.”
