Of course you describe their worst day.
My daughter is capable of walking with crutches. That is her best day. On her worst day, she can’t walk at all, meaning she needs help with pretty much everything and relies on a wheelchair. The benefits she is entitled to means we can provide the things for her which protects her independence, which in turn protects her mental health.
Without those benefits, we could not provide her with the car she needs to be able to get out of the house. (The “free” car that we’ve just had to pay £3,500 for). She can’t travel by public transport because there is no safe route to the bus stop for her (no dropped kerbs, no pedestrian crossings, cars parked on the potholes pavements etc). Without those benefits she is entirely reliant on us for lifts everywhere as she wouldn’t be able to learn to drive, we couldn’t afford to insure a car for her. She wouldn’t have a blue badge to allow her/us to park where she can get out of the car. Ask anyone with a teenage daughter what it would be like for them to need their parent or another adult with them 90% of the time, to have to ask them to help her clean herself after a particularly heavy period, to need to ask for help in the middle of the night when they are unable to turn over in bed, to have to depend on their parents just to go to the cinema with their friends, every single time. Not tell me that if that only happened once a fortnight, that would be ok.
We wouldn’t be able to pay the “disabled tax” for holidays where our costs are around 30% higher than for non disabled families. We couldn’t afford to supplement the basic NHS and LA provision for her.
We have already had to entirely change our working life because after school and holiday provision for disabled children is woefully inadequate. I have 3 meetings at school for her since the beginning of term, and another next week. All this has impacted on our salaries. We’re fortunate to have decent jobs, but the costs of having a disabled child are very high. Even if her worst day is 1/7, or 1/14, you can’t predict when that will be, and the things you have to do to prevent the worst day are time consuming and costly.
Also worth noting, these applications are backed up with medical evidence of a child’s needs. If a claimant over states the problems, the medical records will prove them wrong. Given how damned depressing it is as a parent to sit down and fill out a form that makes it plainly obvious how difficult and different you and your child’s lives are, I don’t know anyone who would willingly put themselves through that.
