Hi everyone, I work supporting children with special needs and have been using this website: www.helpkidzlearn.com/ with a boy who uses switches to access his computer. I can honestly say it's the best online software aimed at SEN I've seen, and has a huge amount of switch access games and stories as well as other options. Some are free, some you need to pay but it's only £1 a month. Looks like it's international too. Just thought it might be useful to some parents on here.
Just wanted to add that I'm not affiliated with them or anything! I hope I don't sound like a sales person, I just know good switch accessible software can be hard to find! Cbeebies also have a "Something Special Out and About" game that is actually 4 games, and video clips, all switch accessible
