Pants Diaper size 4

For most babies, yes. The trifold absorbent core locks in up to 800 ml and holds it for up to 12 hours — through long naps and overnight sleep. The double leak guards and stretchy waist band help keep everything in place even as your baby moves around.

Moomin Baby diapers were co-developed with the Finnish Allergy, Skin & Asthma Association — a collaboration that's been running for over 30 years. Every diaper is free from perfume, lotions, parabens, latex, and chlorine bleaching, rated "Excellent" by Dermatest, and carries AllergyCertified approval. If your baby has sensitive skin, this is exactly the diaper they were designed for.

Yes. The Newborn sizes (NB1 and NB2) are designed specifically for babies from 2 kg, with a special navel cutout to protect the umbilical cord area during the first weeks. The same skin-safe materials and allergy-certified standards apply from the very first diaper.

Go by weight first — each size has a weight range printed on the pack. But the more reliable signal is fit: if you're seeing red marks around the legs or waist, or leaks despite a good seal, it's usually time to size up. When in doubt, go up — a relaxed, snug fit protects better than a tight one.

Every diaper is made at Finland's only diaper factory, running on 100% renewable energy with zero production waste sent to landfill. The pulp is FSC-certified and totally chlorine-free. Packaging is made from 60% recycled plastic and is fully recyclable. It's backed by the Nordic Swan Ecolabel — one of the strictest environmental certifications in Europe.

In Tammisaari, Finland — at the country's only diaper factory, run by Delipap, a family-owned company with 45 years of experience. Every diaper is manufactured and quality-checked there before it reaches you.

Most eco diapers make you choose between performance and purity. Moomin Baby combines both — a trifold absorbent core that holds up to 800 ml with a fully allergy-certified, fragrance-free material list. It also holds a rare combination of three independent certifications: Nordic Swan Ecolabel, Dermatest "Excellent", and Finnish Allergy Association approval. Few diapers on the market carry all three.
