Cumbrian boy Noah Wall's hopes of walking
Noah Wall was born with spina bifida and just a small part of his brain and was not expected to live more than a few days.
By the age of three his brain had grown to 80%.
The seven-year-old from Cumbria has now undergone neurophysics therapy in Australia and can move his foot and it is hoped he will one day be able to walk.
Correction 15 May 2020: This article has been amended to make clear that there was no causal link between Noah's brain growth and his treatment in Australia aimed at helping him learn to walk.
