But if you think you can, try skiing on langlauf ski's and see how it goes. Here is a taste:
There are quite some racing teams who do this to their kids btw. Even into powder. Very hilarious indeed! ;p Makes you appreciate shaped/cambered ski's lol!
Hmmm..... Good that they wear helmets while xc-skiing. Hope that was a compilation of crashes and not how it looks like in real time.
Don't think 1x time at the lift will help much but playing weekly on XC-skis will develop a lot of ski-feel. Average Norwegian kids would have done a lot better than that...
Finding a relatively flat area would be better than going to lifts. Make rollers, small jumps, turns, elements where you have to bend. Play games where you bend down to pick up stuff at speed, throw bags, hunt each other while skating, relays, skate through turns, balance on one ski, ski in hockey-position etc. A lot of stuff will transfer to all types of skiing.
Taking my 8 year old to our first XC-cross race in February and looking forward to it.
Turning on XC-skis is definitively possible, but different than on alpine gear. Of course on can make turns on on reverse chamber/sidecut skis...
