Tips on keeping young dc warm on the slopes?

[Lapinlapin]

We're going on our first family ski holiday in Feb half-term

DC are 3 and 6 and I'm starting to worry about them getting cold and then not enjoying it. We went for a long walk the other day when it was cold (and that's in the UK where it's nowhere near as cold as it will be in the Alps) and the 3 year old got cold and miserable quite quickly.

Admittedly it will be different when he's got base layers on and so on, but just wondering what the best combinations are.

Also, he hates wearing coats and anything bulky (often I have to settle for him wearing a body warmer)
When we're skiing, obviously coat wearing will just have to be non-negotiable, but I'm really not looking forward to the battle. He's pretty strong-willed!

I like 'Joha' or 'Cosilana' or 'Fub' for good kids warm thermal layers. All worn all year around as pjs, layers or regular long sleeve tops back home

And these. In sizes baby to teen so all ages really. Really good for £15

I would recommend spending a lot on gloves. Last time we were skiing it was their hands that were cold and wet. We bought goretex gloves in resort and it made a massive massive difference to how cold they felt.

Don't wear thin socks under your ski socks, they will inevitably wrinkle and cause bruising. I also don't like all in ones for kids. If they Wee themselves then an all in ones takes longer to dry, plus you're having to take a jacket and the all in one. Also much more difficult going to the loo.
