Toddler Ski Recommendation?

I've got twin infant girls and am planning how I will introduce them to skiing. I figure the first season will not be much more than "stand-up" sledding. But hopefully as they get stronger we can work on adding some control for the second season.

My question is around gear and what other folks would recommend. Most "kid" skis I'm finding seem much too long for toddlers. The Lucky Bums toy skis (compatible with snow boots) seems like a decent option, but I imagine learning turns would be more difficult with these skis and standard rigid ski boots (even if they don't fit right) would be helpful to a child who has just learned to walk.

What equipment have others had success with?
How well do boots need to fit at a young age?
Any recommendations for helmets?
Any other suggestions for successful introduction to skiing at a young age?

Thanks!

I'd say that stand-up sledding is probably not a realistic plan. I would have been happy with my 3 year old just taking a few steps on the snow, instead of just standing there crying. We had some kind of lucky bum thing which were quite useful for walking around the living room, and my daughter did have fun with that and was a sufficient intro to skiing. At 4, I bought her some actual skis and boots. And she had a good time on the snow at that age.

Have some patience, they gotta walk before they can ski.

My son is just about two and we've had fun with these:

He's had fun walking around the house with them and we've taken him out to flat areas and pushed him around while wearing them.  We haven't taken him to one of the "magic carpets" yet but plan to before the end of winter if we can find a sufficiently warm and sunny day.  I imagine that at best this would involve snowplowing very slowly with him between our legs.

I got the lucky bums and Elisa got some pretty sweet double boots from the thrift store. The boots have been way more beneficial in any sort of progression that Todd has made recently. He just recently slid on the lucky bums instead of slipping out and landing on his rear end. I don't think that I'll have a decent review on the lucky bums until after next season. Our motto is that if he is having fun....

We have been bringing my 2.5 year old out to Summit West to "ski" the greens.

Found some 80cm skis on craigslist which work great for her. The boots are too big but leaves room for socks that dont fit right without giving her foot pain and ruining our whole day. And since she isn't making turns as much as just a balance and the occasional pizza pie she doesnt need much more.

Picked up the Lucky Bum backpack with leashes which have worked really well. Need the leashes to stop her on the slope and the backpack is great for loading her on and off the chair as I can pick her up by the handle and ski on/off the chair with my little sack of potatoes.
