This ManyMonths sleeping bag can make a real difference if…

• you're looking for a solution to keep your baby warm while sleeping, but classic sleeping bags are often bulky, sleeveless, and let heat escape (to the point of needing to add a top);
• you'd like to rock your baby without having to take them out of the sleeping bag and then put them back in once asleep, and without struggling with a padded sleeping bag that they slip out of;
• you want to feel your baby against you, and not a padded layer between you (even for breastfeeding, without taking baby out of their sleeping bag);
• you're looking for a versatile garment: a sleeping bag at night, then a nightgown / pajamas upon waking, while staying warm;
• you want to be able to transport your baby (stroller, car, quick trip) without necessarily having to change them immediately;
• you want a long-lasting nighttime solution, without having to change sizes every three months;
• you'd like to reduce the frequency and amount of laundry;
• you're looking for a natural, ecological, and truly healthy material for your child.

A light, warm, and non-bulky sleeping bag

The ManyMonths sleeping bag is a long-sleeved sleeping sack made of pure merino wool, designed like a second skin: it's very light, not bulky, yet truly warm and comfortable. It provides stable warmth without "over-bundling" the baby, while allowing them real freedom of movement.

A single layer, to easily adapt it: worn directly on the skin (even in cool summer), or supplemented with a wool or wool/silk bodysuit/shirt depending on the season and room temperature.

Adjustable, evolving, truly well-designed

This sleeping bag was designed to last and adapt to growth, thanks to very specific details:

• sleeves that can be rolled up,
• neckline adjustment for the first few months,
• an extension (included) to attach with snap buttons to gain length and prolong use.

It slips on like a dress / long t-shirt: over the head, or through the legs, whichever is most convenient for you.

Without the extension, it can then become a nightgown or a very long t-shirt for an older child, extending the garment's lifespan far beyond the "baby" period, and up to 3-4 years with just one product!

Practical at night, practical outdoors

A detail that changes everything: you can change the diaper without removing the sleeping bag, by simply opening the bottom part (via the extension). At night, this is a huge comfort gain: baby stays warm, and you're quicker.

It also works very well in a stroller or car seat: the bottom strap can pass between the snap buttons of the extension, leaving some snaps open, which allows for adjustable closure.

Safety and freedom of movement

A sleeping bag is recommended for safe sleeping, keeping baby's legs covered and warm, while allowing them to move freely. With this model, baby can move their legs, turn over, move around in their bed, all while remaining covered.

And for rocking moments, it's particularly pleasant: baby can snuggle against you without a thick padding separating you.

Why merino wool is ideal for sleeping

Merino wool allows the skin to breathe, helps wick away moisture, and helps maintain a comfortable temperature: neither too hot nor too cold. This allows the baby to stay dry and comfortable more often, even when the temperature varies.

The long sleeves can be rolled up initially, or left as mittens to prevent baby from scratching themselves or waking up with a start.

Made of soft, pure merino wool, in stretch knit, with soft seams: comfort designed for fragile and sensitive skin.

Available colors: 

These colors are from previous collections, but I still wanted to offer them in the store.
For me, these are truly essential pieces - and their usefulness remains the same, regardless of the color.

 Seabreeze Teal (ocean blue-green), Driftwood Taupe (heathered beige)

One size:

 total length approx. 80cm, "dress" length (without detachable part) approx. 57cm

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