DLA Application for Grandson....Need help?

I've been a member now for about 2 years & with the help of the expert advice of the community I have a 15-0 win rate for Mandatory Reconsiderations & Lower Tier Tribunal appeals.
However, when it comes to myself I seem to be a little less lucky, sitting at 0-2.
My grandson's came to live with my wife and our family nearly 4 years ago after suffering abuse while with their mother. The eldest grandson, now 9, has a number of issues that we have sort help to give him a better quality of life.
He suffers from Enuresis, of a severe nature, weak ankles which he has to where insoles to help him walk correctly. His main problem is his 'fight or flight' issue which he has a constant throughout his daily life after what he had gone through.
He qualified for DLA after the first application based on the issues at the time, and on the review has been turned down. I spoke to the department in Blackpool on this matter and they agreed that a Mandatory Reconsideration should be sort. I did this.
They have still turned the reconsideration evidence as they don't deem him as in need of support based on the school ticking one box on a form, that he is in full awareness of his surroundings and road sense.
Ticking the box is a joke, he has no road sense and we need to take him everywhere by car due to the fear of him getting hurt or running off to strangers.
I am prepared to take this to the Lower Tier tribunal but need some help as to what I have missed as to arguing my grandsons case??

I look forward to any insights or further questions on this matter.

Keep up the fight for those who need the help & the battle for justice.

Hi Gordon

My email is not hidden in my preferences. I put it up for ease, put sorry if it breaches any code of conduct on the forums.
I would be open to advice on this as I seem to fall down when its for ourselves.
Thank you

Hi Gordon

Sorry for only replying now.
I have spoken with the school when we attended a LAC meeting last Tuesday.
The teacher in question has apologised for making the error and has placed in writing to the same effect, albeit brief.
I spoke to DLA and they have said that if I send proof from the school that it was an error on the form they will look at it again as per the M.R. route, however, said to put my Appeal in as well which can be cancelled if the M.R. is upheld to reinstate the award.
I will keep you appraised on the situation feel free to email me at my email if you think further guidance would help.
Thank you for you insights, and once again I am sorry for the delay in responding to you.
Regards
Mark
