The safest approach in cool weather is to dress your baby in layers. Keep the baby's neck/shoulder area
By checking regularly, you can make sure that it is neither too hot nor too cold.
Quick Guide
Golden rule: Multiple thin coats instead of one thick coat.
Control point: Not hands or feet, but neck/chest.
Ideal room temperature for home: Generally 20–22 °C.
While sleeping: No hats or loose blankets; use a sleeping bag (TOG).
Outside: Wind and humidity increase the “felt” cold; add a wind-blocking layer.
Car seat: No puffy coats; fasten the harness over the baby, not over the layers. A blanket can be placed over the seat.
Layered Dressing
1. Base layer (skin contact): Thin, breathable 100% organic cotton short/long sleeve bodysuit.
2. Mid layer: Interlock/rib overalls or fine knit/sweatshirt.
3. Outer layer: Cardigan or wind/water repellent clothing depending on the weather
4. Accessories: Hat (outside), thin socks/booties. Hats are not worn while sleeping.
Dressing According to Room Temperature in the House
Room Temperature Recommended Clothing Sleeping Bag (TOG)
24–22 °C Thin body + thin overalls 0.5–1.0 TOG
22–20 °C Thin body + long sleeve jumpsuit/pajamas 1.0–2.0 TOG
20–18 °C Body + overalls + thin cardigan 2.0–2.5 TOG
<18 °C Body + overalls + warm outer coat (consider warming the room first) 2.5–3.5 TOG
Tip: If the back of your neck is warm and dry, it's ideal; if it's sweaty, it's overdressed; if it's cold, it might be one less layer.
When Going Out: Combinations Depending on the Weather
Cool & windy (10–15 °C): Body + overalls + windproof jacket + beanie + booties.
Cold & dry (5–10 °C): Body + overalls + knitwear/raised mid-layer + water/wind repellent outer layer.
Very cold/rainy (<5 °C): Go outside for a short time; raincoat/softshell + blanket. Be careful not to get wet. Car seat safety: No thick coats should be placed under the belt. Fasten the baby in normal layers; place a blanket over the belt.
Temperature Management During Sleep (Safe Sleep)
TOG: The thermal insulation degree of the sleeping bag; it is selected according to the room temperature.
No loose blankets → prefer a sleeping bag.
No hat (risk of overheating).
Example (20–22 °C): Body + overalls/pajamas + 1.0–2.5 TOG sleeping bag.
Control: If the neck is sweaty, lower the TOG or remove one layer.
Fabric Selection (For Sensitive Skin)
100% Organic Cotton (GOTS): Breathable, provides comfort all day long.
Muslin: Very breathable; temperature regulation is easy with the number of layers.
Rib/Interlock: Flexible, ideal for daily use.
OEKO-TEX Standard 100: It is a safety indicator tested for harmful chemicals.
Common Mistakes
Wearing a single thick layer → sweating → feeling cold.
Using a hat/scarf while sleeping → overheating and safety risk.
Judging by looking at hands/feet → misleading; look at the back of the neck/chest.
Fluffy coat on the car seat → creates a belt gap.
Mini Combination Examples
Indoors 22 °C: Thin body + interlock overalls + 1.0–1.5 TOG sleeping bag (while sleeping).
Outside 10–12 °C, windy: Bodysuit + overalls + thin knitwear + windproof coat + beanie.
19 °C room at night: Body + overalls + 2.0-2.5 TOG sleeping bag.
