As an adult I used to ski at both Hillingdon and Wycombe ski slopes. I loved it and also went on a skiing holiday with BSCD (British Ski Club for Disabled).
I found that I couldn't ski standing because due to my diplegia that affects my legs I couldn't get my legs in the position they need to go into to snow plough. Theu tried toe clips on my skis which forced my ski into that position and made my legs go into that position. But I screamed the place down as it felt like my legs were being broken!!
After that I started using what they call a sit ski so I could dtill ski but I was sat down doing it. I loved it. So if you want to try it with your 3.5 year old give it a try.
Hope that helps.
Thanks Helen, yeah we're going to give it a go as soon as the lessons start up on Sundays at Hemel. Sit ski for him to start with and then maybe standing.... he has diaplegia so not sure about the snowplough - in some ways snowboarding may be better but he needs to be 6 or 7 for that.
