Disability Living Allowance
The mobility (walking) part has two rates. To get the high rate, £64.50, the child must be unable to walk, or only able to walk for a very limited distance, or at a limited speed or manner.  Children who are blind or have no feet qualify.  A child who has intelligence and behaviour problems so that they cannot be left alone can  get the high mobility rate, if they get the highest rate of care. If they get the high rate it can be used to get a car or wheelchair from  Motability. To get the lower mobility rate, £24.45, they have to show that they need to be guided or watched most of the time.
