Rent or borrow the outer layers for a first trip. Jackets and salopettes are the expensive items, they are the ones children outgrow fastest, and plenty of resorts and rental shops hire them. Buy the base layers and socks, because those are cheap, they are the layers that actually determine whether your child is warm, and hiring intimate layers is not a thing.
**Q: How many layers should a child wear under their ski jacket?** A:One thin base layer and one or two thin mid layers. The number matters less than the adjustability: two thin mid layers you can add and remove one at a time beat a single thick one, because a child's heat output changes enormously between a lift ride and a run.
**Q: Are thicker socks warmer in ski boots?** A:No, and usually the opposite. A ski boot is sized for a foot plus a thin sock. Extra fabric compresses the foot, restricts the blood flow that actually warms the toes, and removes the pocket of still air that was insulating. Use one thin ski sock pulled smooth.
**Q: Mittens or gloves for a five-year-old?** A:Mittens. Fingers grouped in one chamber share heat and expose less surface area than five individually wrapped fingers, and mittens are far easier to get onto a cold hand. Pick a long cuff that goes over the jacket sleeve.
**Q: Is it true you lose most of your heat through your head?** A:No. Vreeman and Carroll addressed this in the BMJ in 2008: the head loses heat roughly in proportion to its share of body surface area, not the half or more the myth claims. The advice to cover a small child's head still holds, though, because a young child's head is a far larger share of their total surface area than an adult's. Paediatric burn charts put an infant's head near 18% of body surface against roughly 9% for an adult.
**Q: What is the one thing people forget to pack?** A:A second pair of mittens. Wet mittens end more children's ski days than cold weather does, they get wet from playing rather than from the forecast, and no amount spent on the first pair prevents it. Keep the spares dry in a backpack and swap at lunch by default.
**Q: Do children need goggles or will sunglasses do?** A:Goggles. They seal against wind, they stay on in a fall, and they work with a helmet. Sunglasses do none of those three reliably. Bring a spare pair or a spare lens if you can, since a scratched or fogged lens on day two is a miserable problem.
**Q: Should we use hand warmers on young children?** A:They are useful, with one rule: never against bare skin. They hold heat long enough to cause a slow burn at a temperature that does not trigger the usual pain warning, so the people most at risk are those least likely to notice or say something. Put them in a mitten's outer pocket or between the sock and the boot liner, and check the skin at lunch.
