Essential First Layer

This ManyMonths tank top is the essential first layer, the one that directly influences the body's thermal balance.

It helps keep the skin dry. Moisture is absorbed by the wool, while the dried air can then be warmed by body heat and retained by the next layer, for example, a knit or thicker wool.

The first layer is the most important: it is in direct contact with the skin and conditions the body's entire thermoregulation. It must therefore be natural and breathable.

Comfortable to wear

soft and supple knit
does not scratch
pleasant directly on the skin

Easy to combine

perfect with:
→ a t-shirt
→ a ManyMonths skirt
→ leggings or longies
matches the ManyMonths skirt

→ easily creates cohesive outfits

Durable and evolving design

simple and unisex cut
grows with the child
easily integrates into a minimalist wardrobe

Colors 2026/27:

Toasted Coconut
Warm and soft beige, slightly textured. Soothing neutral, easy to pair.

Foggy Black
Softened black, deep but not harsh. Nuanced charcoal effect, elegant and discreet.

Twilight Blue
Intense night blue. Deep, enveloping, very chic.

Nebula Pink
Vibrant but softened pink. Light, cheerful, and easy to integrate.

The visuals presented show the product worn and in use, but some colors are not contractual and come from previous collections.

Photos in Foggy Black and Toasted Coconut correspond to the colors carried over in this new collection if the product concerned will be available in those colors.

Adventurer: 1–2.5 years (80–98 cm)
Conqueror: 3–5 years (98–110 cm)

Every child grows at their own pace.
I recommend choosing the size according to the height in centimeters rather than age.

ManyMonths have their own size guide

Newcomer: 0–3/4 months (50–56/62 cm)
Charmer: 3–6/9 months (62–68/74 cm)

Enthusiast: 8–10 years (128–134/140 cm)
Lionheart: 10–12/13 years (140–152/158 cm)

Then older children can choose adult clothing MaM or MaD in size S, then M...

How to choose the right child size for pre-order (delivery in September)

For pre-orders, it is always necessary to anticipate the child's growth between today and receipt. With ManyMonths, it's even simpler:
their sizes are adaptable and cover several classic sizes. This allows for real room to grow, without the risk of the garment being too small upon receipt.

Simple rule:

never skip a size (because you would be skipping several classic sizes)
choose at least the next size up
sometimes the same size the child would wear today - only if it has just been started

• Oeko-Tex Standard 100 Class 1 certified
• No Superwash or other treatments
• Mulesing-free wool (yarn made exclusively for Babyidea)
• Non-toxic dyes suitable for natural fibers and sensitive skin

Pure, untreated wool garments do not need to be washed often.

• Regular care

- Regular airing outdoors (outside if possible, or in front of an open window)
- Rest after each use: hung on a hanger or drying rack, not left in a ball
- Spot clean stains with room temperature water and Ulrich gall soap or genuine Marseille soap

• Full wash (rare)

- Hand washing strongly recommended despite "Machine Washable" label
- Cold or room temperature water
- Ulrich Natürlich or Disana liquid wool detergent
- Wash temperature = rinse temperature
- Do not wring, roll in a towel
- Dry flat, away from direct sunlight and any heat source

• Maintaining Lanolin

- Lanolin treatment (every 2-3 washes) or lanolin impregnation (every 3-4 washes) from time to time to preserve self-cleaning and thermoregulating properties.
- Follow the instructions on the product sheets for these products

ManyMonths / MaM / MaD clothing is manufactured for the Finnish brand Babyidea by EcoTextile / HempValley (Denmark/China), a workshop specializing in natural fibers and GOTS certified since 2008 – still a rarity in China and elsewhere. Production adheres to ILO social standards (voluntary work, prohibition of child labor, fair wages, safety, and regulated working hours), and each component is OEKO-TEX® Standard 100 Class I certified, making it suitable for contact with babies' skin.

The dyes are produced by certified workshops and tested by independent laboratories. This partner was chosen based on verifiable criteria: technical expertise, traceability, and social guarantees. The goal is transparent and sustainable manufacturing, prioritizing responsible production practices over mere geographical proximity.

• Can it be worn directly on the skin?
Yes, as a base layer.

• Is it useful in winter?
Yes, for layering.

• Is it suitable for school?
Yes, it helps regulate temperature.

• Is it not too warm in summer?
No.
Merino wool is thermoregulatory: it helps the body maintain a stable temperature, even when it's hot. Worn sleeveless and as a light layer, this tank top remains breathable and comfortable in summer, without overheating.

It's a garment that's underestimated... until you start using it. It allows for very fine adjustment of the fit without adding an entire layer. And children love the little pockets.

• Please hand wash!

This simple gesture – and rarely necessary – helps preserve the garment's beautiful fit and size over time.
Gentle care also helps maintain the product's high quality, which can be a real advantage if you ever wish to resell it.

ManyMonths clothes are easily passed down from family to family, and their second-hand value often remains very appealing.
Well-cared for, used for a long time – then resold, this garment can thus become one of the most economical pieces in your child's wardrobe.

Babyidea / ManyMonths / MaM

The Babyidea story begins in Finland, in the Helsinki region, as a Scandinavian family business guided by a simple idea: to design products that are truly useful in everyday life and consistent with natural parenting.

MaM® Design's beginnings date back to 2001, during Bettina's maternity leave; she was then a university lecturer. At that time, physiological babywearing was virtually unknown in Europe, and suitable clothing was practically nonexistent. The first creations were therefore born from a concrete need: to make life with a baby easier, without compromising on comfort or materials.
ManyMonths clothes that grow with the child - are born.

The brand has grown alongside its children: from a few boxes stacked in a bedroom serving as a makeshift workshop to a 500 m² logistics space near Helsinki, and then to a network of distributors and boutiques across Europe. Despite this evolution, the objective remains unchanged: to develop sustainable, practical, and respectful solutions in partnership with companies that share the same values.

Following this principle, the manufacturing of ManyMonths, MaM, and MaD clothing was not based on geographical criteria but on technical and human factors. The choice fell on EcoTextile / HempValley (Denmark/China), a workshop specializing in natural fibers that has been operating for nearly twenty years with high standards of traceability and social responsibility. GOTS certified since 2008—a still rare certification—the manufacturer also adheres to the ILO's international labor standards. Each component is OEKO-TEX® Standard 100 Class I certified, and the dyes are tested by independent laboratories.

This partnership reflects the brand's philosophy: prioritizing expertise, transparency, and verifiable guarantees over superficial proximity. The objective remains the same as from the outset: to create clothing designed to last, safe for children, and consistent with a more responsible lifestyle, from design in Finland to manufacturing.

The MaM / MaD collection for adults was born in 2017 to meet the growing demand from parents to finally be able to wear the same wool as their children in ManyMonths.

*******

My business began with the purchase of a simple ManyMonths pure wool bodysuit in 2012. That's when I truly discovered what wool could be like in everyday life. Then, as I outfitted my children with the entire collection, another realization dawned: I wanted to talk about it, explain it, and share it with the world!

That's how my shop was born. This brand was the direct origin of my business, and over the years I have also been very actively involved in its development in France, while influencing certain product developments thanks to feedback from the field.

It all started thanks to Bettina. I will always be grateful to her for these clothes that have accompanied my children - and me - throughout all these years.

All Babyidea products

Brand pride: exemplary and GOTS-certified manufacturing workshop

EcoTextile workshop, GOTS certified, still very rare

All MaM® and ManyMonths clothing has been produced for over 25 years in the brand's partner workshop in China, a rare GOTS-certified workshop specializing in eco-friendly clothing. Dedicated, closely monitored production, designed for natural fibers and more responsible fashion.

A structured work pace + a shared "slow fashion" vision

8-hour days, with at least 6 days off per month. Manufacturing is part of a slow fashion approach, supported by their long-standing partner EcoTextile (HempValley / European management): priority is given to natural fibers and more responsible materials, with a focus on durability, for clothes that can truly be worn, passed on, and loved for a long time.

A mature, protected team with real rights

All employees are over 21 years old, have health insurance and the right to paid maternity leave. These are clear social foundations, which are as important as the quality of the knitwear.

Safe and fair working conditions

No ambiguity here: safe working conditions, stable organization, and salary announced at +20% above the local level. Because "ethical" clothing always starts with respect for the people who make it.
