Marvelous for your. We do claim for our autistic DS, we get DLA and Carers Allowance, I work (part time currently as I was made redundant last year and have had to take what I could get), DH works long hours for fuck all (essentially self employed) so he can do school runs when DS goes in, is in the house with him when he doesn't go in etc.
We are considerably worse off than when we were both working full time, and DH is working a lot harder, sometimes until 1 or 2 am to meet deadlines.
The DLA currently pays for counselling (CAMHS wouldn't do anything despite DS being suicidal and self harming, school could only refer for six sessions provided by a vol sec org) and clothes as DS chews his to rags, and as we had an underspend it meant we could get the car repaired recently (no car would mean no school at all, no going to hospital appointments etc), occasional emergency Costa visits when out if DS gets dysregulated (visiting anywhere new involves knowing where the Costa is in case DS can't cope.)
(I'm sure someone will want to have a go about the underspend - the DLA was originally used to take DS swimming once or twice a week as it was the only way he'd wash or get changed, then he started refusing to go. This coincided with puberty hitting, the EBSA starting up again and being suicidal and starting to self harm.)
