Blue badges

Hi my daughter who is 14 years is getting more and more challenging to manage and when were out and about she can become aggressive towards myself or self harm, esp wen trying to cross roads or car parks are the worse. My daughter also has ADHD and is constantly talking to herself and is totally unaware do dangers around her. I've tried to apply for a blue badge and because she can walk we don't meet the criteria. And the same with higher rate mobility. Has anybody else got this problem or better still managed to get one with circumstances being similar ??????
