Benefits

Im new to the forum - I have 3 boys, 14yrs, 11yrs (diagnosed asd,adhd + chromosmal abnormalities, global delay), 9yrs old (undiagnosed but under camhs). 

I have 2 questions the first regarding DLA - I have had DLA for middle son more or less since birth, varying levels at varying times of development, at the moment middle rate personal care and lower rate mobility. He has always struggled with sleeping, nightmares etc and has recently started on melatonin. Someone told me i should reapply as its a change of circumstances but im concerned with todays climate they will reduce the ammount. There are a few other things that seem to be getting worse with him too, such as sensory problems and ticks. Is it really worth it? and would i have to reapply or just inform of changes?

The second question is regarding carers allowance grant, I have never applied for it before and would like to try and get some out door play equipment for him, does anyone know where is good value for money and that supplies swings for older/heavier kids, as you will understand i think toys for my boys have to be just a bit more durable. Ive looked but most websites are expensive or commercial.

Thanks in anticipation
