As this is a pre-order, photos of the new collection are not yet available.

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

The photos in Foggy Black and Toasted Coconut correspond to the colors carried over in this new collection, for the relevant products.

Sizes:

Adventurer: 1–2.5 years (80–98 cm) - only Callisto Moon, Moondust Blue

Conqueror: 3-5 years (98–110 cm)

Innovator: 5–7.5 years (110-128 cm)

Enthusiast: 8–10 years (128–140 cm) - only Foggy Black, Moondust Blue

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

Miracle: Premature (44–50 cm)
Newcomer: 0–3/4 months (50–56/62 cm)
Charmer: 3–6/9 months (62–68/74 cm)
Explorer: 6–12/18 months (68–80/86 cm)
Adventurer: 1–2/2.5 years (80–92/98 cm)
Conqueror: 3–4.5/5 years (98–104/110 cm)
Innovator: 5–7/7.5 years (110–122/128 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, you always have to anticipate the child's growth between today and reception. With ManyMonths, it's even simpler:
their sizes are adaptable and cover several classic sizes. This leaves a real margin for growth, 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)
  • always choose at least the next size up
  • sometimes the same size the child would wear today - only if it has just been started
Composition

• Natural Merino wool 380 g/m²
• Oeko-Tex Standard 100 Class 1 certified
• No Superwash treatment or any other treatment
• Guaranteed mulesing-free wool (yarn made exclusively for Babyidea)
• Non-toxic dyes suitable for natural fibers and sensitive skin
• 55% Hemp / 45% organic cotton for the trimmings

Maintenance tips

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 and not left in a ball)
- Spot clean stains under ambient water with Ulrich gall soap or real Marseille soap

• Full wash (rare)

- Hand washing is highly recommended despite the "Machine washable" label
- Cold or ambient water
- Ulrich Natürlich or Disana liquid wool detergent
- Washing temperature = rinsing temperature
- Do not wring, roll in a towel
- Dry flat, away from direct sunlight and any heat source

• Lanolin maintenance

- Treatment (every 2-3 washes) or lanolin impregnation (every 3-4 washes) from time to time to preserve self-cleaning and thermoregulatory properties.
- Follow the advice given on the product sheets

Manufacturing & Ecology

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.

Frequently Asked Questions

• Are knee reinforcements really useful?
Yes, they significantly extend the lifespan of the pants.

• Is it suitable for all seasons?
Yes, merino wool naturally regulates temperature.

• Is it warm for winter?
Adding ManyMonths leggings underneath will make a warm duo for children who are sensitive to cold.

• Doesn't merino wool itch?
The merino wool used for baby clothes is very fine and soft. It is suitable even for sensitive skin. Proper care and maintaining lanolin remain a decisive step for the natural softness of any wool.

Yuliya's Tips

• For me, this is THE essential item for children, right after the ManyMonths longies. While leggings aren't really an everyday standalone item, these joggers immediately look like "real clothes": comfortable, practical, and perfectly suited for daily life. I was really happy to see them arrive in the collection a few years ago in a jogger version, because this type of versatile pant was exactly what was missing, and it has no equivalent on the market! And a little bonus I love: it pairs super well with the ManyMonths women's joggers, for a simple, stunning, and ultra-comfortable parent/child duo.

• Please hand wash!

This simple gesture - and rarely necessary - helps preserve the garment's good fit 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 clothes are easily passed down from family to family, and their second-hand value often remains very attractive.
Well-maintained, 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.
