Every child grows at their own pace.
I recommend choosing the size according to 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)

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

For pre-orders, it's always necessary to anticipate the child's growth between now and receipt. With ManyMonths, it's even simpler:
their sizes are adjustable and cover several standard sizes. This allows for significant growth margin, with no risk of the garment being too small upon receipt.

Simple rule:

never skip a size (because you'll be skipping several standard sizes)
always choose at least the next size up
sometimes the same size the child would wear today - only if they've just started wearing it

• Non-toxic dyes suitable for natural fibers and sensitive skin
• Patches made of 55% hemp / 45% organic cotton

Untreated pure wool clothing does not need to be washed often.

• Routine 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 real Marseille soap

• Full wash (infrequent)

- 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 sun and any heat source

• Maintaining Lanolin

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

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.

• How to wear it: alone or as a base layer?
Both. It can be worn alone against the skin, or over a ManyMonths wool t-shirt, or a wool/silk layer if you are looking for 100% natural fiber layering.

• Is it suitable for school?
Yes, perfect for indoor/outdoor transitions.

• Can it replace a jacket?
Yes, in mid-season, or indoors.

• Can it be used all year round?
Yes.
Merino wool naturally regulates body temperature and remains comfortable in winter as well as in mid-season, not to mention cool summers.

• Isn't merino wool scratchy?
The merino wool used for baby clothing is very fine and soft. It is suitable even for sensitive skin. Proper care and maintaining the lanolin is a decisive step for the natural softness of all wool.

• This is the kind of piece you grab without thinking.
When you're wondering "is it chilly or not?" → this is the vest you reach for.

• Hand wash, please!

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

ManyMonths garments are easily passed down from family to family, and their second-hand value often remains very good.
Well-maintained, used for a very 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.
