How to dress your baby in winter? The question arises as soon as the first cold weather arrives. New parents often worry about not dressing them warmly enough… or, conversely, overdressing them. Between forgetting a hat, choosing a sleep sack that's too warm, or selecting the wrong bodysuit, finding the right balance can be difficult. This comprehensive guide helps you put together a comfortable, safe, and suitable winter outfit for your little one—combining common sense, softness, and natural fabrics.
Because every detail counts, dressing your baby for winter is also about learning to observe, adjust, and find the right balance. Far from relying on ready-made solutions, it's primarily about understanding how their body reacts and prioritizing just the right amount of warmth. The kind that comforts without suffocating. The kind that allows your baby to move, breathe, and grow peacefully. A simple and tender art, made of wool, cotton, and care.
Baby and winter: understanding their thermal needs
Newborns and young babies don't yet regulate their body temperature as efficiently as adults. Their thin skin, proportionally larger body surface area, and small muscle mass mean they cool down quickly. When it's cold, they expend a lot of energy just to maintain their core temperature—hence the importance of appropriate, breathable, and well-layered clothing.
Why are toddlers so sensitive to the cold?
A baby loses up to 30% of their body heat through their head and extremities. Because they move very little and don't yet shiver to keep warm, their comfort depends on us. The areas to check are simple: the nape of the neck and the chest. If the nape of the neck is warm and dry, everything is fine. If it's cold, add a layer; if it's damp, remove one. Red cheeks, cold hands, or unusual crying are also subtle signs to pay attention to.
Generally speaking, it's recommended to dress a baby in one more layer than an adult in the same situation. This doesn't mean swaddling them, but simply compensating for their limited ability to generate heat. Several thin, breathable layers are better than one thick garment that would restrict their movement or prevent them from regulating their temperature.
The ideal temperature at home
Inside, there's no need to overheat. The ideal temperature for a baby's room is between 18 and 20°C . In living areas, 19 to 21°C is perfectly sufficient. Air that is too hot and dry irritates the mucous membranes, while too many blankets promote sweating and therefore... subsequent chills. Ideally, the room should be aired for a few minutes every morning, and a humidifier should be used if the air is too dry. A healthy and comfortable environment helps the baby sleep and breathe better.
The main principles for dressing baby in winter
Dressing a baby in winter is first and foremost a matter of observation and common sense. The goal isn't to pile on layers, but to adapt their clothing to the temperature and activity level. The three-layer rule, simple and adaptable, remains the most reliable way to guarantee comfort and safety.
The three-layer rule, explained simply
This method, inspired by mountaineering, is perfectly suited to toddlers. It keeps baby warm while easily adjusting their clothing to suit different situations (walks, naps, heated indoors, etc.).
- First layer — softness to the touch: a long-sleeved bodysuit in cotton or fine merino wool. This first layer absorbs moisture and keeps baby's skin nice and dry.
- Second layer — just the right amount of warmth: a cardigan, a knitted vest, or a light sweater, preferably in merino wool. This natural fiber retains heat while allowing the skin to breathe. It regulates temperature without ever overheating.
- Third layer — outer protection: a coat, a flight suit, or a footmuff, depending on the weather. It acts as a barrier against wind, cold, or moisture while remaining comfortable.
Materials to favor (and those to avoid)
The quality of the materials is just as important as the number of layers. In winter, you need gentle warmth, the kind that breathes and envelops without confining. Natural fibers are your best allies.
Materials to prioritize
- Merino wool: the key material for cozy winters. Ultra-fine, it doesn't itch and maintains a stable temperature. It insulates against the cold while wicking away perspiration. Whether in a bra, blanket, slippers, or hat, it provides a vibrant warmth that's never stifling.
- Organic cotton: soft, breathable, perfect for the first layer. It absorbs moisture and is gentle on sensitive skin.
- Cashmere: luxurious and light, it warms without being heavy.
- Fleece linen: surprising in winter, it can be used for loungewear or soft and airy sleeping bags.
Materials to avoid
- Synthetic fibers (polyester, acrylic, thick fleece)
- Wools that are too rough

Going out with a baby in winter: the right things to do
In a stroller, in the car, or in a baby carrier
When using a stroller: use a warm footmuff.
In a car: never put a pilot suit under the harness.
In a baby carrier: the parent's warmth counts as a diaper.
Protect without confining
The key to good winter dressing is breathing.
Avoid common mistakes
- Overdress baby
- Neglecting the extremities
- Forgetting to remove the hat inside
- Use synthetic materials
- Clothes that are too tight or too big
And what about premature babies?
Premature babies have even more specific thermal needs. Merino wool is ideal.
In short: just the right amount of heat, comfort above all
Three thin layers, natural materials, observation.
