Dressing a newborn – the first weeks

Freshly born, temperature regulation is still a work in progress: newborns get too cold and too warm faster than older children. Hence the simple guideline for the first weeks: one thin layer more than you would wear yourself in the same room.

In short: bodysuit + romper are the basics. One layer more than you, no hat indoors, and always feel the neck – warm & dry is perfect.

The basics for indoors

The clothing essentials

You don't need a huge wardrobe. Tried and tested: bodysuits (short- and long-sleeve), rompers, a few thin cardigans, socks and little hats, a sleep sack in the right size – and for outdoors, depending on the season, a boiled-wool suit (cold) or a light sun hat (warm). Buy little in newborn size (50/56) – babies grow at breakneck speed.

The neck check

Hands and feet are almost always cooler in newborns – that's normal and not a sign of being cold. Feel the back of the neck or the upper back instead: warm and dry means everything's fine. Sweaty means one layer off, cool means one layer more.
