Almost all parents worry about whether their child is too cold or too warm. Since babies cannot regulate their body temperature properly during their first months of life and cannot yet tell you how they feel, there is one simple and reliable way to check if they are comfortable:
The Neck Check – Your Best Guide
Forget about cold hands or feet!
Babies' and toddlers' hands and feet often feel cool because their circulation is still developing. This does not necessarily mean they are cold. Instead, gently feel the back of your child's neck:
- Warm and dry: Perfect! Your child is comfortable.
- Hot and damp (sweaty): Your child is probably too warm and may be at risk of overheating. Remove one layer of clothing, such as a jacket or sweater.
Cool or cold: Your child is too cold and needs an extra warm layer or a hat.
Other Signs to Watch For
In addition to the neck check, your child's body gives you other helpful clues:
- Restlessness or fussiness: Babies often become unsettled or cry when they feel too hot or too cold.
- Pale or flushed skin: A pale face or bluish lips can indicate that your child is cold. A bright red face or head is often a sign of overheating.
Why Natural Fibres Make Things Easier
This is where natural fibres such as disana organic merino wool and our wool/silk blends truly stand out. Wool is a remarkable natural temperature regulator. Its fibres contain millions of tiny air pockets that act like a built-in climate control system.
They provide excellent insulation when it's cold while allowing excess heat and moisture to escape when temperatures rise.
As a result, children wearing disana clothing are much less likely to overheat than in garments made from polyester or even pure cotton. Natural fibres help balance everyday temperature changes, keeping your child comfortable throughout the day.
Layering is the secret to dressing your child comfortably in every season. The idea is simple: instead of one thick garment, dress your child in several thin layers. The air trapped between the layers provides excellent insulation and helps retain body heat.
If your child gets warm while playing or the sun comes out, simply remove a layer. When the temperature drops again, add it back on.
For the best results—especially during the colder, wetter months—the layering system is divided into three layers.
The 3 Layers of the Layering System
1. The Base Layer (Next to the Skin – Moisture Management)
The base layer should fit close to the body and wick moisture away from the skin to help prevent your child from getting cold after sweating.
Best choice: A bodysuit or undershirt made from a wool/silk blend or pure merino wool.
Why? Wool can absorb up to one-third of its own weight in moisture without feeling damp and continues to keep your child warm even when it is slightly wet.
Cotton is less suitable because it absorbs moisture, stays wet against the skin, and can make your child feel cold.
2. The Mid Layer (Insulation – Retaining Warmth)
The mid layer traps body heat and provides insulation. It should fit loosely to allow insulating air pockets to form.
Best choice: A sweater, slipover, or knitted trousers made from soft wool knit.
Why? Knitted wool is wonderfully stretchy, highly breathable, and naturally traps plenty of air within the knit structure, providing excellent warmth without overheating.
3. The Outer Layer (Weather Protection – Shielding Against Wind and Rain)
The outer layer protects your child from wind, cold, and light rain.
Best choice: A jacket, snowsuit, or trousers made from boiled wool.
Why? The felting process creates a dense, durable fabric that blocks wind, insulates against the cold, and naturally repels light rain while remaining breathable. This helps prevent overheating. In prolonged heavy rain, simply add a lightweight waterproof shell over the boiled wool trousers.
A Simple Rule of Thumb
Dress your child using the "plus one" rule. Babies and toddlers who are not yet very active—such as those in a stroller or baby carrier—generally need one more layer than you do to stay warm. Once children are running, climbing, and playing, they usually only need the same number of layers as an adult.
The honest answer is: Yes and no.
Whether a boiled wool overall or jacket will keep your child warm enough in the middle of winter depends on two main factors: what they're wearing underneath and how windy it is.
Our disana boiled wool overall is intentionally designed with only a partial lining (around the hood and neck) and does not contain thick polyester padding. While boiled wool offers excellent insulation, the fabric itself is not completely windproof in icy, cutting winds.
Here are two real-life examples:
- -15°C (5°F) on a calm winter day: We've spent hours playing in fresh snow with our own children on bright, freezing days, and nobody felt cold. Without wind, the wool insulated beautifully, and the children's movement kept them comfortably warm.
- +8°C (46°F) on a stormy autumn day: A much milder temperature can actually feel colder if there's a strong wind. When cold wind blows through the tiny air pockets in the wool, your child may start to feel chilly despite the higher temperature.
So the key question isn't just "How cold is it?"—it's also "How windy is it?"
Is it suitable for spring and autumn?
Absolutely!
The disana boiled wool overall is an ideal companion for the changing weather in spring and autumn. Combined with a lighter layering system—for example, a lightweight long-sleeved top underneath—it keeps your child comfortably warm without overheating during play.
What if my child gets cold?
It's completely normal to worry. Learning how to dress a baby or young child for different weather conditions is something every parent discovers over time.
Just like adults, children all experience temperature differently. Some are little "cold-natured" children, while others warm up very quickly.
Our advice: Try it out without worrying too much. Start with short everyday outings—a walk to the bakery, a visit to the playground or a stroll with the grandparents—and see how your child feels.
It's always a good idea to pack an extra knitted cardigan, wool jumper or a small blanket in the stroller or changing bag. That way, you can easily add another layer if your child needs a little extra warmth.
What about windy or rainy weather?
You don't have to leave your boiled wool overall or jacket at home just because the weather turns wet or windy.
Simply pull an unlined waterproof rain jacket and waterproof trousers over the boiled wool clothing.
This gives you the best of both worlds:
- The waterproof outer layer keeps out wind and rain.
- The boiled wool underneath continues to provide warm, breathable insulation.
This combination keeps your child cosy, dry and comfortable, even on cold, wet and windy days, without overheating.
For the cold, wet months, we always recommend keeping a simple, unlined rain jacket and waterproof trousers in your child's wardrobe. They are the perfect complement to your boiled wool clothing.
Together, they make the ideal combination for wet, muddy adventures and offer several practical benefits:
The perfect 2-in-1 solution
Simply pull the waterproof layer over your child's boiled wool jacket or overall. The outer layer keeps out wind and rain, while the pure merino wool underneath continues to provide warm, breathable insulation without causing your child to overheat.
This combination is ideal for everything from rainy walks to the muddiest winter play sessions.
Flexible and budget-friendly: Simple, unlined rainwear is usually much more affordable than heavily insulated outdoor jackets.
It also gives you far more flexibility: on dry days, your child can simply wear their cosy boiled wool jacket. When the weather turns wet or windy, just add the waterproof outer layer.
Keeps muddy messes away: On particularly muddy days, waterproof trousers help keep most of the dirt off the boiled wool clothing, so there's much less brushing and cleaning afterwards.
A tip when buying rainwear: Choose waterproof clothing with a smooth inner lining. Avoid rough coatings or mesh linings, as these can rub against the soft boiled wool fabric and cause unnecessary wear over time.
A more sustainable choice: If sustainability is as important to you as it is to us, consider choosing rainwear from brands that focus on environmentally responsible materials and production. Today, there are many excellent sustainable options available, allowing you to create an outdoor outfit that's kind to both your child and the planet.
Absolutely! Whether your baby spends most of the day in a sling, a baby carrier or snuggled up in a pram, boiled wool clothing is an incredibly practical companion.
The natural properties of wool really come into their own in both situations.
In a baby carrier: Temperature regulation and warmth where it's needed. Many parents worry that their baby will become too warm in a carrier because they are sharing body heat.
Helps prevent overheating: Wool naturally regulates temperature far better than synthetic fabrics such as polyester fleece. It allows excess heat and moisture to escape, helping to prevent uncomfortable heat build-up between you and your baby while keeping them comfortably warm.
Keeps little legs and feet warm: When babies are carried, their trousers naturally ride up a little, leaving their legs and feet more exposed to the cold. A boiled wool overall with fold-over cuffs helps keep these sensitive areas cosy and protected.
Easy to pack when you don't need it: At some point during your outing, you may want to take your baby out of the carrier—for a nappy change, some playtime or simply a break. Because boiled wool is surprisingly lightweight and flexible, the jacket or overall can be rolled up compactly and easily fits into a changing bag or backpack.
In a pram: A naturally comfortable climate. Boiled wool is just as practical in a pram, especially as the weather can change quickly during a walk.
The perfect combination: On particularly cold days, simply combine your baby's boiled wool clothing with a warm footmuff.
Easy to adapt: If the weather becomes milder or the sun comes out, you can simply unzip the footmuff or remove it altogether. Your baby will still be comfortably dressed in their boiled wool overall without overheating.
As with all outdoor clothing, layering is the key. Boiled wool provides a warm, breathable base that can easily be adapted to changing temperatures throughout the day.
Especially at a nature kindergarden, where children spend hours outdoors in nature in all kinds of weather, wearing the right clothing is absolutely essential. It’s all about finding the perfect balance between warmth, room to move and breathability. Many nature kindergarden already provide parents with specific clothing lists – and for good reason!
Why all-in-one suits are often impractical in the forest
One-piece suits are wonderful for babies, but at a nature kindergarden they can quickly reach their limits. When you need to get to the toilet quickly in the forest toilet trailer, a full suit can often get in the way and takes too long to take off.
The better solution – Our boiled wool trousers without braces
That’s exactly why we developed our new boiled wool trousers without braces. They can be pulled up and down in no time, fit comfortably thanks to the elasticated waistband, and don’t restrict movement when climbing and playing.
The unbeatable forest duo - Boiled wool underneath, waterproof trousers on top
For wet and muddy days, experienced parents particularly favour the combination of boiled wool clothing and lightweight waterproofs.
Cosy and warm underneath: The boiled wool trousers and boiled wool jacket keep your child comfortably warm without causing them to overheat during active play.
Windproof and waterproof on the outside: A simple, sturdy pair of waterproof trousers and a waterproof jacket worn over the top protect the boiled wool fabric from rain, mud and tree resin.
Why wool beats cotton in the forest
Many parents swear by pure new wool. A wool jumper is far better suited to everyday life in the forest than a traditional cotton sweatshirt.
The problem with cotton: As soon as cotton becomes damp from sweat or mist, it absorbs the moisture, dries extremely slowly and can quickly leave your child feeling cold.
The strength of wool: Our pure new wool jumpers continue to provide reliable warmth even when they become damp, while helping to transport moisture away from the body.
Pay attention to the cuffs: Even with wool clothing, many manufacturers use elasticated cuffs made from cotton. In the forest, these can quickly become soaked when they come into contact with damp soil or wet grass – resulting in cold, clammy hands and wrists.
That’s why our disana cuffs are also made from pure, protective wool!
