Caring for children's cotton: the guide to making it last (and pass it on)

Good cotton can dress two, three children in a row. Provided you don't mistreat it in the machine.

A child's garment lives dangerously: grass, chocolate, felt, carrot puree, and washes twice a week. The good news is that cotton is a robust fibre. What wears it out is almost never the child; it is the machine set too hot, the tumble dryer, and fabric softener. Here is how we do it at home, and why.

30 °Care sufficient in 95 % of cases

Before the first wash

Always wash a new garment before putting it on, especially for a baby: this removes manufacturing and transport residues. A 30 °C cycle, inside out, without fabric softener. Bright and dark colours should be washed separately for the first two times.

For newbornsRompers, bodysuits and bibs that touch a newborn's skin can be washed at 40 °C for the first few weeks if you wish. Beyond that, 30 °C is more than sufficient.

Washing: the five steps

Inside out, fastenings closedPress studs and zips damage neighbouring knits. Inside out, the outside of the garment no longer rubs against the drum: colours hold and pilling disappears.
30 °C, cotton or delicate cycleHot water does not remove more stains: it is the soaking time and the detergent that act. On the contrary, it sets proteins (milk, egg, blood) and fatigues the fibres.
A half-dose of liquid detergentToo much detergent leaves a film that stiffens the cotton and irritates sensitive skin. Liquid rather than powder: it rinses better at low temperatures.
No fabric softenerIt coats the fibre in a greasy film: the cotton absorbs less, breathes less, and bibs become waterproof in reverse. For softness, half a glass of white vinegar in the rinse compartment; it leaves no smell once dry.
Moderate spin800 rpm is sufficient. Beyond that, fibres break and garments come out deeply wrinkled.

Drying: where it all counts

The tumble dryer is the number one enemy of children's cotton: it shrinks the knits, felts the fleece and breaks the fibres (the lint in the filter is your garment). A drying rack means 24 hours of patience and years of extra life.

Woven (shirts, dresses, trousers)On a hanger or peg, smoothed out well by hand: you will almost not have to iron.
Knits and sweatshirtsFlat on the drying rack, in shape. Hung while wet, they stretch at the shoulders.
Muslin and cotton gauzeWithout heavy spinning, spread out without stretching: the crinkle returns on its own when drying.
In a real hurry?Tumble dryer at a low temperature, 15 minutes, then finish drying in the air.

Un sweat séché à plat garde sa forme. Suspendu mouillé, il grandit avant l'enfant. — A sweatshirt dried flat keeps its shape. Hung while wet, it grows before the child does.

Stains: act fast, with cold water

The single rule: never hot water on a fresh stain. Rinse with cold water from the reverse side of the fabric to push it out, then treat.

Stain	What works	To avoid
Grass	Marseille soap rubbed on dry, 30 min, then wash	Bleach (yellows the cotton)
Chocolate, tomato sauce	Cold water, washing-up liquid, 30 °C wash	Rubbing in circles (spreads it)
Felt-tip pen, pen	70° alcohol dabbed on the reverse, on absorbent paper	Hot water (sets the ink)
Banana, carrot, purées	Soak in cold water + bicarbonate, 1 h	Let dry before treating
Milk, regurgitation	Immediate cold rinse, then enzymatic detergent	60 °C cycle
Mud	Let dry, brush, then wash	Rub while wet
Blood	Cold salt water, then soap	All heat

The grandmother's trick that worksThe sun is a natural and free bleaching agent: a white bodysuit spread outside after washing regains its brightness. Colours, however, prefer the shade.

The case of muslin and organic cotton bodysuits

Cotton gauze (nappies, bibs, summer dresses) softens with every wash: it is normal for it to feel a little rough when new. No ironing: the crinkled texture is its signature. For untreated organic cottons, the same rules apply, using a fragrance-free detergent to preserve the advantage of a non-irritating fibre.

A word from Ana

Ana, mother of Sasha and Noah

At our home, children's laundry goes into a washing bag inside out, at 30 °C, and dries on the balcony drying rack. Sasha is still wearing a cardigan bought for his cousin five years ago. It has never seen a tumble dryer.

Store, pass on, repair

A clean and dry garment is stored folded, in a dry place, away from direct sunlight. For pieces you are keeping for a second child: washed, thoroughly dried, in a cardboard box or a cotton bag (never closed plastic, which yellows). A button sewn back on, a knee reinforced with an iron-on patch: ten minutes that add a season.

Durability is not just about how a garment is made. It is also about how we take care of it.Our conviction

In summary

Inside out, 30 °CZips closed, half-dose of liquid detergent.
Never use fabric softenerWhite vinegar during rinsing if you want softness.
Air dryingFlat for knits, hanging for woven fabrics.
Treat stains while cold, immediatelyRinse from the inside out, then treat according to the table.
