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

The visuals shown display the product being worn and used, but some colors are not contractual and are from previous collections.

Photos in Foggy Black and Toasted Coconut correspond to colors that are being reissued in this new collection for the relevant products.

Sizes:

Newcomer: 0–3/4 months - 50 to 56/62 cm

Charmer / Explorer: 3–12/18 months - 62 to 80/86 cm

Adventurer: 12–30 months - 80 to 98 cm

Every child grows at their own pace.
I recommend choosing the size based on the child's 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)

Older children can then choose adult clothing from MaM or MaD in size S, then M...

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

For pre-orders, you always need to anticipate the child's growth between today and receipt. With ManyMonths, it's even simpler:
their sizes are adjustable and cover several standard sizes. This provides real room for growth, without the risk of the garment being too small upon receipt.

Simple rule:

  • never skip a size (as you would be skipping several standard 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

• 380 gsm natural merino wool
• Oeko-Tex Standard 100 Class 1 certified
• No Superwash or any other treatment
• Non-mulesed wool (yarn made exclusively for Babyidea)
• Non-toxic dyes suitable for natural fibers and sensitive skin
• 55% hemp / 45% organic cotton waistband

Maintenance tips

Garments made of pure, untreated wool 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 real Marseille soap

• Full Wash (infrequent)

- Hand washing is highly 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 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 for these items.

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

• Is it comfortable with cloth diapers?
Yes, the cut is designed for that.

• 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 is a decisive step for the natural softness of any wool.

Yuliya's Tips

• For me, this is the 3rd essential ManyMonths item, right after the body/shirt and the longie.
Worn alone or over these two pieces, this romper has replaced a multitude of classic, often unnecessary and uncomfortable clothes.
At home, out and about, as pajamas... it did it all.
I simply managed with two rompers, airing them out in turns.
Honestly, one of my best ManyMonths investments. As a mom, I recommend it wholeheartedly.

• Hand wash, please!

This simple gesture - and rarely necessary - helps preserve the garment's good shape 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 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.
