Atmungsaktive Babykleidung aus Musselin und Bio Baumwolle Wärmestau beim Baby im Sommer vermeiden mit MARY by sticklett und atmungsaktiver kleidung

What should I dress my newborn in summer?

Newborns can't regulate their body temperature well yet – they cool down faster but are also sensitive to heat. Especially on hot days, the question arises: What should I actually dress my baby in at 30 degrees? Learn here how to dress your newborn optimally in summer while providing protection, comfort, and a good feeling.


Why the right clothing is so important in summer.

Especially in the first few months of life, temperature plays a crucial role. Babies cannot yet regulate excess heat well and are particularly sensitive to heat. They sweat less effectively, their skin is thinner, and their body surface area is larger in relation to their weight. Heat builds up faster – especially on the head and in the torso. Overheating is also considered a significant risk factor in connection with Sudden Infant Death Syndrome (SIDS).

What should I dress my baby in when it's hot?

Even in summer, newborns need protection – especially for their arms and legs. Long, light clothing protects delicate skin from the sun and at the same time helps to keep body temperature stable. The decisive factor is not the quantity, but the right material such as organic cotton, bamboo or muslin and the right combination.

An often underestimated point is headwear: Babies lose a lot of heat through their heads, and at the same time, they are particularly sensitive to the sun there. A light, temperature-regulating hat balances temperature and provides reliable protection. Materials like hemp are particularly suitable – as with the sticklett hemp hat for newborns: It is breathable, naturally antibacterial, and supports a balanced skin climate without overheating.

Breathable materials are key.

Opt for light, breathable fabrics like organic cotton. They allow your baby's skin to breathe, absorb moisture well, and prevent heat buildup.

Baby clothing made of muslin is also highly recommended: The loosely woven fabric is extra airy, feels pleasantly soft on the skin, and its structure ensures natural air circulation.

Avoid clothing with a high synthetic fiber content, such as polyester: It stores heat, promotes sweating, allows air to circulate less effectively, and moisture remains on the skin. The baby overheats without really cooling down – a dangerous heat buildup can occur, which should be avoided especially in newborns.

Stay flexible with the layering principle.

The layering principle is ideal for summer: several thin layers that you can flexibly put on or take off depending on the temperature. Thoughtfully designed combinations of wrap bodysuits and light rompers or trousers are particularly practical.

This way, you can quickly dress and undress your baby when it gets warmer or cooler, without unnecessary stress for you and your baby.

Your feeling for the right clothing, supported by the ladybug MARY.

With MARY by sticklett, the vital sensor system in a ladybug design, you also have a good feeling: You can see how your baby's temperature develops and easily recognize via the app whether a layer is too much or too little.

Caution in the stroller!

A frequently underestimated risk is the stroller. Even if your baby is sleeping peacefully, the temperature inside can quickly rise – especially in the shade or if the stroller is covered. This creates a heat build-up that is barely visible from the outside and can be dangerous for your baby.


MARY by sticklett also helps you here: Changes in the temperature curve become visible. This way you know if your baby is prone to overheating or is cold and can react in time before it becomes critical. For relaxed walks and outdoor stays even on warm days.
