❓ FAQ — Frequently Asked Questions

What kind of onesie for a newborn?
For a newborn, opt for a 100% cotton onesie with easy opening (side or front) and snap closure. This white cotton romper ticks all the boxes: softness, ease of dressing, and optimal comfort.

How to dress a baby in winter?
In winter, the onion-peel technique is recommended: long-sleeved cotton bodysuit + cotton romper + appropriate TOG sleep sack. This 100% cotton romper is the ideal mid-layer.

What is the difference between a romper and a baby onesie?
A romper has shoulder straps and leaves the arms free, while an onesie covers the entire body. This model is a long-sleeved onesie with integrated straps — the best of both worlds for baby.

Why choose cotton for baby clothes?
Cotton is the most recommended material by pediatricians for babies: natural, breathable, hypoallergenic, and soft. Avoid synthetics that can irritate newborns' sensitive skin.

What size to choose for a newborn?
An average newborn (3-3.5 kg, 50 cm) wears 0-1 month. If in doubt, take one size up — babies grow very quickly! Consult our size guide to choose the right size.
