It is the question behind almost every organic baby clothes purchase: is organic cotton actually better for babies, or is it just better marketing?
We make organic cotton baby clothes, so you'd expect us to say yes. The honest answer is more useful than that: organic cotton is genuinely better in some specific ways, makes no difference in others, and the word on the label matters far less than the certification behind it.
The short answer. For the clothes that sit against your baby's skin all day, certified organic cotton is a sensible choice. It is grown without synthetic pesticides or fertiliser, and if it carries GOTS certification it is also processed without chlorine bleach, formaldehyde-based finishes or restricted azo dyes.
What it is not is a treatment for anything. The cotton fibre itself is not chemically different once it is spun, and the thing doing most of the work for your baby is the certification of how the fabric was processed, not the word 'organic'.
What 'organic cotton' actually changes
There are two separate stages to think about: how the cotton is grown, and how it is turned into fabric.
Growing. Organic cotton is grown from non-genetically-modified seed, without synthetic pesticides, herbicides or fertiliser. Farmers use crop rotation, compost and natural pest control instead. This is mainly a benefit for the soil, the water and the people who farm it, and it is the part most organic claims are talking about.
Processing. This is the part that touches your baby. Raw cotton has to be cleaned, bleached, dyed and finished before it becomes a sleepsuit, and organically grown cotton can still go through all the same chemistry as conventional cotton. Only a whole-chain standard like the Global Organic Textile Standard (GOTS) controls what is allowed at every one of those stages.
'Organic cotton' on a label tells you about the farm. 'GOTS certified' tells you about the farm and the factory. For baby clothes, the second one is the claim worth looking for.
We've gone into the farming side in more depth in organic vs conventional cotton: is it worth it?
Is organic cotton better for baby skin?
All cotton, organic or not, has the qualities that make it good next to a baby's skin: it is soft, it breathes, it absorbs moisture and it washes well at low temperatures. A conventional cotton sleepsuit is still a cotton sleepsuit, and it is a perfectly reasonable thing for a baby to wear.
Where certified organic cotton can be better is in what is not on the fabric. GOTS restricts the dyes, bleaches and finishes used in processing, so you are not relying on a residue washing out. Many conventional garments are given easy-care or anti-crease finishes; a GOTS garment cannot be.
One honest caveat: what you wash clothes in often matters as much as what they are made of. Detergent residue and fabric softener are common culprits when a baby's skin reacts to clothing. Our guide to washing baby clothes covers the simple changes that help: 30°C, non-bio, less detergent, an extra rinse and no softener.
Is organic cotton better for eczema?
This is where we want to be especially careful, because no fabric treats eczema, and you should be wary of anyone who says otherwise.
What we can say is that UK eczema guidance generally recommends loose cotton clothing next to the skin and avoiding wool and rough fibres, and the NHS lists some fabrics and washing detergents among common triggers. That advice is about cotton generally, not organic cotton specifically.
So if your baby has dry or eczema-prone skin, soft, breathable cotton with as few chemical finishes as possible is a sensible choice, and GOTS certification is one way to check the 'few finishes' part. But it sits alongside, not instead of, the emollients and advice from your GP or health visitor. If your baby's skin is sore, cracked or not settling, please speak to them.

Is organic cotton worth it?
Organic cotton costs more to grow and certify, and that shows up in the price. Whether it is worth it depends on where you spend it.
If budget is tight, we'd put organic money into the base layers: bodysuits, sleepsuits and sleeping bags that sit against the skin for hours at a time. Cardigans, coats and anything worn over other layers matter less.
It is also worth thinking in cost per wear. A well-made sleepsuit worn twice a week for three months gets around 26 wears, and if it survives to be handed on to a second baby, more than 50. Durable fabric that keeps its shape through that many washes can end up cheaper per wear than a bargain piece that doesn't make it past the first child. We worked through the numbers in how much it really costs to dress a baby in the first year.
How to tell what you're actually buying
Labels in baby clothing are a bit of a minefield. Here is what the common ones mean.
| Label | What it tells you | What it doesn't |
|---|---|---|
| 'Organic cotton' | Some or all of the cotton was grown organically | How much organic cotton is in it, or how the fabric was processed |
| GOTS 'organic' | At least 95% certified organic fibre, with chemical, environmental and social criteria across the whole supply chain | Anything about the brand's other, uncertified products |
| GOTS 'made with organic' | At least 70% certified organic fibre, same processing rules | What the other 30% is: check the composition label |
| OEKO-TEX Standard 100 | The finished product was tested for a list of harmful substances | Whether the fibre is organic or how it was farmed |
| 'Natural' or 'eco' | Very little: these are not regulated terms on clothing | Almost everything |
If a brand says GOTS, you can check their certification on the public GOTS database. A genuine certified brand will be happy for you to.
So, is organic cotton better for babies?
For the planet and for the people who grow it, yes, clearly. For your baby, certified organic cotton gives you soft, breathable fabric without the chemical finishes that conventional processing allows, which is a good reason to choose it for the layers worn closest to the skin. It won't fix a skin condition, and a well-washed conventional cotton bodysuit is not a bad thing to put on a baby.
Our view is simple: buy fewer, better pieces, choose certified organic for the base layers, and hand them on when you're done. That is what we design every Lucy & Sam piece for.

Common questions
Is organic cotton better for babies?
For the layers worn against the skin, certified organic cotton is a sensible choice because it is processed without chlorine bleach, formaldehyde-based finishes or restricted azo dyes when it carries GOTS certification. It is not chemically different as a fibre, and it is not a treatment for any skin condition.
Is organic cotton better for sensitive skin?
Cotton in general is often recommended for sensitive skin because it is soft and breathable. GOTS certified organic cotton adds restrictions on the chemicals used in processing. Washing matters too: use a mild, non-bio detergent, an extra rinse and no fabric softener.
Is organic cotton better for eczema?
No fabric treats eczema. UK guidance generally recommends loose cotton clothing next to the skin and avoiding wool and rough fibres. Organic cotton meets that, and GOTS certification limits chemical finishes, but always follow advice from your GP or health visitor.
Is organic cotton worth the extra cost?
It is most worth it for base layers like bodysuits, sleepsuits and sleeping bags that sit against the skin for hours. Thinking in cost per wear, durable pieces that can be handed down often work out cheaper than they first look.
Is organic cotton softer than regular cotton?
Not because it is organic. Softness comes mostly from the fibre quality, the knit and the absence of stiff finishes. Many people find GOTS cotton feels soft from the first wash because it has no chemical coating to wash out.
Every Lucy & Sam piece is made from 100% GOTS certified organic cotton and designed in the UK to be worn, washed and handed down.
