Pushchair help please

Hi everybody, nice to meet you.

My son is 5 and a half and still needs a pushchair, however, because of his sensory issues it has to have a hood otherwise cue massive meltdown and we can't go out, and therefore the Maclaren major is no good for him Unless i can get a hood for it which will be added expense. Not only that but our local wheelchair services say it is a restraint to put him in a pushchair, he doesn't "need" it and is able bodied So won't help - unfortunately about right for our area whwire completely useless and apart from a fantastic school everything else is a fight..... Probably familiar to a lot of you I suspect.

So, back to the pushchair, not a cheap prospect as you can imagine! He is already 26kgs and 130cm tall so most ordinary pushchairs are out although I have found a couple that will take up to 35kgs in USA so would be suitable for him.....

Any ideas where to go to see if I can get funding (I'm a single parent student with an older child to support too and money is a little tight until I qualify) or suggestions of pushchairs that aren't the major?

Thanks in advance for your help and advice..... I could ask forever about issues etc but one step at a time hey lol :)
