Dressing your baby in spring & autumn
The in-between seasons are the supreme discipline: cool in the morning, mild at midday, plus wind and the odd shower. This is exactly where the layering principle shows its strength – several thin layers that you simply add or remove depending on the weather.
In short: a long-sleeve bodysuit as the base, a middle layer such as a sweater or romper and a light jacket within reach. Take a hat along – babies lose a lot of heat through the head and ears.
Chart: spring & autumn by temperature
| Temperature | Recommendation |
|---|---|
| 18–22 °C mild | Long-sleeve bodysuit · trousers or romper · thin hat · light jacket within reach |
| 13–17 °C cool | Long-sleeve bodysuit · sweater + trousers or a warm romper · light jacket · hat · socks |
| 8–12 °C cold | Long-sleeve bodysuit · boiled-wool or fleece suit · jacket · hat over the ears · footmuff in the stroller |
Think about wind & rain
Wind chills more than the thermometer suggests – a windproof outer layer helps. When it's wet, use a water-repellent jacket or a rain cover for the stroller. Still make sure it doesn't get too warm: prefer breathable materials and check the neck regularly.
