Gentle fabrics for baby skin
Which natural fabrics feel best on a baby and why, what GOTS and OEKO-TEX labels really tell you, and how careful washing can help sensitive skin.
A baby’s clothes are worn closer to the skin, and for more hours of the day, than almost anything else they will own. It is natural to want those fabrics to be as gentle as possible. This guide looks at the natural fibres that feel best on a baby, why they do, what labels and certifications actually tell you, and how washing can help sensitive skin.
Cotton, from airy muslin to smooth Pima
Cotton is the familiar starting point, and two forms deserve a closer look. is a light, loosely woven cotton. The name is traditionally traced to the city of Mosul. Its open weave makes it airy and soft, which is why muslin cloths are such constant companions in the first months, over a shoulder, on a lap or beside the cot.
Pima cotton is an cotton, named after the Pima people of the American Southwest, where it was cultivated. Staple simply describes the length of the individual fibres. Long fibres make a smoother, stronger yarn, and smoothness is exactly what you want against new skin.
The construction matters as much as the fibre. Muslin is woven, while bodysuits and sleepsuits are usually knitted, often as cotton jersey, which gives them the stretch that makes dressing a baby easier. Both can be gentle; they simply do different jobs in the wardrobe.
When you compare cottons, let your hands decide as much as the label. A fabric that feels smooth and supple to you, without a stiff or rough surface, is likely to feel the same to your baby.
Merino wool, softer than its reputation
Wool has a reputation for scratchiness that merino does not deserve. Merino wool comes from merino sheep, and its fibres are fine, typically under about 24 micrometres for garments worn next to the skin. That fineness is why it feels soft rather than scratchy.
Merino also helps regulate temperature, which is why it is often chosen for base layers and cardigans. Warmth still depends on how many layers your baby wears and on the room, so dress for the conditions rather than for the fibre, and follow the care label closely when you wash it.
Bamboo viscose: read the label closely
Descriptions of bamboo fabrics can give the impression of a plant fibre taken straight from nature. In fact, bamboo viscose is a : it is processed chemically, so it is not the same as a natural bamboo fibre.
That does not make it unpleasant to wear, and many people like its smooth feel. It simply belongs in a different category from cotton or wool. If natural fibres matter to you, the composition label is the place to look, not the name on the packaging.
What certifications actually tell you
Softness is the first test, but the label tells you the rest. Two certifications appear on baby clothes more often than most, and they answer different questions.
GOTS, the Global Organic Textile Standard, was launched in 2006. It certifies textiles made from organic fibres along the whole processing chain, and it includes environmental and social criteria. In other words, it speaks about how the fibre was grown and how the fabric was made.
OEKO-TEX Standard 100, introduced in 1992, tests textiles for harmful substances. Its covers articles for babies and toddlers up to 36 months and has the strictest limits. It speaks about the finished textile, not about whether the fibre is organic. The two are complementary, and a garment may carry one, both or neither.
It also helps to separate certifications from descriptions. Words such as natural, pure or gentle on a swing tag describe a product, but they are not in themselves a certification. A named certification is the more precise information.
Softness is the first test, but the label tells you the rest.
Washing and sensitive skin
Wash new garments before wearing. Fragrance-free detergents and an extra rinse can help sensitive skin, and it makes sense to use the same gentle routine for the bedding and muslin cloths that touch your baby’s face.
- Wash every new piece before the first wear.
- Choose a fragrance-free detergent.
- Add an extra rinse if your baby’s skin is sensitive.
- Follow the care label, especially for merino and other wool.
Fabrics and washing can only do so much. If your baby has eczema or a persistent rash, ask a paediatrician or dermatologist for advice rather than changing fabrics and detergents by trial and error. They can look at the skin itself and help you decide what is best to put next to it.
The gentlest wardrobe is rarely the largest. A few well-chosen pieces in soft cotton or fine merino, washed with care and checked from the inside, will serve a baby better than a drawer full of clothes chosen for how they look on the hanger.

- A light, loosely woven cotton fabric; the name is traditionally traced to the city of Mosul.
- Extra-long staple
- Cotton with especially long individual fibres, which spin into a smoother, stronger yarn, as with Pima cotton.
- Micrometre
- One thousandth of a millimetre, the unit used to describe how fine a wool fibre is.
- Regenerated cellulose fibre
- A fibre made by chemically processing plant cellulose into new filaments, as with bamboo viscose.
- Product class I
- The OEKO-TEX Standard 100 category for articles for babies and toddlers up to 36 months, with the strictest limits.
Questions and answers
Can babies wear merino wool next to the skin?
Fine merino is made for wearing next to the skin. Its fibres are typically under about 24 micrometres, so it feels soft rather than scratchy, and it helps regulate temperature. Every baby is different, though. If you notice redness or a rash, take the garment off and ask a paediatrician or dermatologist for advice.
Is an organic certificate the same as a test for harmful substances?
No. GOTS certifies textiles made from organic fibres along the whole processing chain, including environmental and social criteria. OEKO-TEX Standard 100 tests textiles for harmful substances, and its product class I, for babies and toddlers up to 36 months, has the strictest limits. The two answer different questions, and a garment may carry one, both or neither.
What helps if my baby’s skin is sensitive?
Wash new garments before wearing, use a fragrance-free detergent and consider an extra rinse. Soft fabrics with flat seams and labels that do not rub are kinder to the skin. For eczema or a persistent rash, ask a paediatrician or dermatologist rather than changing products by trial and error.
