What should I dress my newborn in summer?

The first hot season with a baby leaves many parents wondering: Is a bodysuit enough? Do they need long sleeves? And how do I prevent my child from overheating? Newborns, in particular, cannot yet regulate their own body temperature – so the right clothing in summer is crucial for safety, comfort, and healthy baby sleep.

Less is more? Not quite!

Summer doesn't automatically mean wearing as little clothing as possible. Babies have thinner skin than adults – they cool down faster and are more sensitive to the sun. The rule of thumb: wear one more layer than you normally wear.
• A light cotton bodysuit is often sufficient inside.
• Outside, airy long-sleeved bodysuits or thin rompers are a better choice; they also provide protection against UV rays.
Tip: Shade is a must, but UV rays are still present there. Therefore, it's better to wear long clothing instead of leaving your skin exposed.

Onion look even in summer

Yes, the layered look doesn't just work in winter. Several thin layers are more flexible than a single thick piece:
• If it gets too hot → take off your layer.
• If it cools down → add another layer.
This will prevent your baby from sweating or freezing and effectively prevent heat build-up.

Sweating in summer? Not with natural fibers

Synthetic fibers like polyester or polyamide often appear light and airy, but their low air permeability can quickly lead to heat buildup, skin irritation, or allergies. Particularly dangerous: Overheating is a risk factor for SIDS (sudden infant death syndrome).
Breathable materials like organic cotton or bamboo are better. They absorb moisture, are gentle on the skin, and allow air to circulate.
👉 That's exactly why we use certified organic cotton for our rompers , bodysuits and sleeping bags - light, airy and skin-friendly.

Practical summer essentials for babies

To ensure your baby gets through the hot days safely and relaxed, these basics have proven to be effective:
• Lightweight bodysuits (short & long sleeve): Long sleeves are better for newborns. Breathable, with adjustable cuffs and scratch protection, they'll fit longer.
• Summer sleeping bags made of organic cotton: No thick filling, airy and safer than blankets.
• Crawling pants with turn-up function: Allow freedom of movement and protect the skin while playing.
• Muslin cloths or muslin clothing : multi-talented – as sun protection, breathable and comfortable to wear.

Baby sleep in summer

It's also important to avoid overheating at night. The ideal room temperature is 16–20°C. Instead of a blanket, opt for a cotton sleeping bag.
