Understanding how to dress a newborn during the first months is one of the most common concerns among new parents. Newborn babies are not yet able to regulate their body temperature effectively, which is why it is essential to choose clothing suited to the season and follow the layering principle.
In this guide, you will discover how to dress a newborn in winter, spring, summer and autumn, how to tell whether your baby is too hot or too cold and which materials to choose.

The most important rule when dressing a newborn is to use layers.
The principle is simple:
âś” choose several lightweight layers
âś” rather than one single heavy garment
A classic example:
A bodysuit as the first layer
A bodysuit is the essential first layer during the first months. To understand how many you should buy, read our guide on how many bodysuits a newborn baby really needs.
A romper or lightweight jumper as the second layer
A blanket when necessary
This makes it easy to adapt your baby’s clothing according to the temperature.
Many parents check their baby’s hands and feet, but these are not reliable indicators.
The correct way to understand whether a newborn is too hot or too cold is to:
👉 touch the baby’s neck or back
If they feel warm and dry → the temperature is comfortable
If they are sweaty → the baby is too warm
If they feel cold → add another layer
When considering how to dress a newborn in winter, the priority is to maintain a stable body temperature.
Recommended clothing:
A merino wool bodysuit
A long-sleeved romper
A lightweight knitted jumper
A blanket for outdoors
Extrafine merino wool is particularly suitable because it is naturally thermoregulating: it helps retain warmth without causing excessive perspiration.
