Start with a soft base layer, add a mid layer as needed, and let the winter jacket protect against wind and cold. The right choice depends on the temperature, wind, dampness, activity, and how long the child will be outdoors.
Layering makes it easier to add or remove a layer during the day. It’s often more practical than one very thick sweater.
How to dress your child in three layers
1. Base layer
The innermost layer should feel comfortable and help keep the child dry. A long-sleeved top, wool underwear, or a soft undershirt can be a good starting point. Wool insulates well on cold days, while cotton should be changed if it gets damp after play.
2. Mid layer
The mid layer is the layer that’s easiest to adjust. Choose, for example, fleece, knitwear, or thin wool. An active child often needs a lighter mid layer than a child sitting still in a stroller or on a long walk.
3. Outer layer
The winter jacket should protect against the weather while leaving room for the layers underneath. When the jacket isn’t tight across the shoulders and arms, the child can move freely, and the layer of air between the clothes provides better insulation.

How to check if your child is dressed warmly enough
Feel the child’s neck or upper back. The skin should feel comfortably warm and dry - not cold, clammy, or sweaty. Cold hands alone don’t always mean the whole body is cold.
Wet or damp clothing should be changed. Young children may have difficulty telling you that they are cold, and the Danish Health Authority recommends paying special attention to young children in cold weather. Read the Danish Health Authority's advice on young children spending time in the cold.
Wool, fleece or cotton?
-
Wool: warm and practical on cold days.
-
Fleece: a lightweight mid-layer that is easy to put on and take off.
-
Cotton: soft and comfortable, but should be changed if it gets wet.
Common mistakes to avoid
- The same amount of clothing every day, regardless of the wind and activity.
- Too many thick layers under a tight-fitting jacket.
- Wet clothes after playing in the snow or rain.
- Judging warmth based only on the hands.

Frequently asked questions
Should children always wear fleece under a winter jacket?
No. On milder days or during active play, a long-sleeved top or a thin mid-layer may be enough.
How do I know if my child is wearing too many clothes?
If the child is sweaty or clammy around the neck or on the back, they are often wearing too many or too warm layers.
Should there be room for multiple layers in a winter jacket?
Yes. The jacket should have enough room for a mid-layer without restricting the child's movement.
