Dressing for 15–18°C outside
Parents don’t experience weather as a single degree — “about 15°C” is how real mornings feel. This guide covers the 15–18°C band, where the outfit usually stays in the same family.
Around 15–18°C, start with a long-sleeve bodysuit, a light jacket or cardigan, and a thin hat.
At the cool end (~15°C): At 15°C, start with a long-sleeve bodysuit, a light jacket or cardigan, and a thin hat. At the warm end (~18°C): At 18°C, start with a long-sleeve bodysuit, a light jacket or cardigan, and a thin hat.
Stroller, carrier, and car seat change the setup slightly — TinyLayers has a mode for each.
The 10-minute chest check
About 10–15 minutes after settling (or outside), feel the chest or back of the neck: warm and dry is right; sweaty means remove a layer; cool means add one. Cool hands and feet alone are normal.
Common mistakes in this band
Matching adult jackets one-for-one often overheats babies. Start with the layers above, then adjust from the chest — not cold hands.
This is general dressing guidance, not medical advice. Every baby is different — for fever, premature birth, or any medical concern, follow your clinician.

This page is for outdoor weather. For crib sleep, use the sleep temperature guides — the room, not the forecast, decides.
