c) Ditch the Poles - You do not need poles to ski until you can parallel ski and most young children aren't there. I don't care that the poles look cool, they are a hinderance and you will all be much happier if neither you nor your learning child have to worry about them. Don't be afraid!
d) Learn on Easy Stuff - I am amazed at how critical it is for parents to advance their child to the next level of slope. This is totally irrelevant to your child's ski learning early on. Easy, bunny, and often free is totally fine. Your child can fall and mess up and learn and advance and never have to go on a chairlift. You will get much more accomplished if your child skis the bunny slope forty times than if he picks his way painfully down an intermediate trail taking half a day to do it. It is YOU who is so hung up on the level of trail. Not your child. Be willing to stay easy.
e) Don't Insist On Skiing Until 4pm - Your money does not come back to you if you push it beyond the limits of your own or your child's physical capabilities. Injuries occur late in the day when the slopes get icy and the skiers get lazy and tired. It is not a crime to quit at 2pm or 3pm.
f) Prepare the Night Before - Searching for that missing glove or neck warmer as you are running out the door gets the day off on the wrong foot. Teach the kids to put their ski clothes and apparatus in the same place and to have it ready for the next day. If you have a spare room in the house, put everyone's ski clothes in a different spot in the room. The next morning, going to your pile of stuff and having it all in one place will make getting ready for skiing easy on everyone.
g) Take a Day Off - If you are going for a whole week, take a day off in the middle somewhere. Allow a day to recharge, try something different, go cross country skiing, ice skating, shopping for new ski clothes or just hang around the hotel if there are things to do there. Your kids are not going to advance as much each DAY as they will each week that you ski. So, there is not a huge difference between skiing 5 days or 6 in terms of skier development, but the sanity of taking a day off will really help everyone to just be excited about the day to go back.
