Refused dla!!!!!

Hi has anyone else been refused dla my son is 8 1/2 has been diagnosed with mild cerebral palsy and incontinence...I got refused dla so asked for a mandatory reconsideration which today has also been refused.. it's so disheartening....he needs more help than a another child his age his muscles are affected in both legs which causes him pain to walk can't walk far gets tired and out of breath can't go up and down stairs on his own can't go outside on his own because he falls over all the time...he still has to wear nappies as he can't control his bladder he wakes up every night with cramps and he has wet the bed through his pull ups...have I got any chance of winning an appeal or am I best to reapply when I have more information the school is now doing him a care plan xx
