Hi Shifter
As a ski instructor myself I thought I could say a few words on this! Ive never taught kids as young as four but taught most ages from 5 and up.
Not sure how it is with other ski schools but the ones Ive taught in, we like to keep adults/parents and ski school separate, so you won’t need to be hanging around and the supervisors won’t want you doing that anyway.
I suppose most instructors I know try to teach kids the same way they would a younger brother or sister, or kids of their own (I don’t have any yet lol).
Also, it makes our job a lot easier if you can get your kid excited and happy about the idea of ski school. I’ve had lots of kids who clearly don’t want to be there and won’t cooperate for the entire class, often some screaming and kicking involved (the kids that is not me!).
Well hope you all have a good time anyway!
