How do I transition my baby from being swaddled?

We recommend sleeping your baby with one arm out of the swaddle wrap for 1-2 weeks, then moving to both arms out, with feet still wrapped for a further 1-2 weeks, and finally, moving to a baby sleeping bag, with both arms and legs having the ability to move freely.

What is the difference between a Cocooi Newborn Sleepbag and a Merino Kids ™ Baby Sleep Bag?

The Cocooi Newborn Sleepbag bag is made from two layers of superfine merino, and is designed for use between newborn and 3 months of age. Merino is proven to improve sleep patterns and encourage feeding and sleeping in newborn babies. The Merino Kids Baby Sleep Bag is lined with superfine merino, but has a 100% cotton outer for added durability, as it is designed for two years of use.

Merino Kids Baby Sleep Bag

Why use a baby sleep bag?

Using the Merino Kids Baby Sleep Bag will prevent your baby from waking due to a drop in temperature after wriggling out of their blankets and getting tangled in their sheets.

Why use merino vs synthetic?

Merino generates heat using any moisture to regulate temperature. If your baby’s skin is moist, merino removes it, releasing it into the atmosphere, thereby keeping your baby warm and dry. Synthetic, on the other hand, may appear to be warm, however garments that contain synthetic don’t breathe, making it more likely for your baby to perspire. This creates a moist environment, which leads to a chill zone next to your baby’s skin. Bacteria are more likely to survive in these conditions.

Why use a Merino Kids Baby Sleep Bag?

The Merino Kids Baby Sleep Bag is a sleeping bag designed specifically for babies and toddlers and uses only 100% natural fibers – superfine merino wool & 100% cotton. It can be taken anywhere, allowing your child to be easily transferred from a car seat or buggy into their crib or bed. It is safe for your child and amazingly practical. A popular alternative to sheets & blankets, the Merino Kids Baby Sleep Bag has passed vigorous fire safety tests and are all labeled LOW FIRE RISK.

The Merino Kids Baby Sleep Bag has many benefits including;

  • Prevents your baby from waking after wriggling out of their blankets.
  • Keeps your baby at a safe and comfortable temperature throughout the night.
  • Merino regulates temperature by removing heat and moisture away from the body and in cool conditions (between four and six in the morning) it insulates.
  • Babies associate the bag with sleep so will settle more easily in unfamiliar surroundings.
  • Safely used by children with allergies, eczema and sensitive skin.

Do I need more than one Merino Kids Baby Sleep Bag?

We strongly recommend the rotation of two sleeping bags – over a six-month period most children sleep on average 3,000 hours and rotating two bags enables you to get the most out of your Merino Kids Baby Sleep Bag . Your Merino Kids Baby Sleep Bag is made from all natural fibers and contains no polyesters so please follow washing instructions carefully.

When should I start putting my baby in a Merino Kids Baby Sleep Bag?

Your baby can go into a Merino Kids Baby Sleep Bag from newborn up until 4 years of age. For the first three months, you may wish to use the dome adjustment system under the arms. When using a Merino Kids Baby Sleep Bag we advise a minimum weight of 7lbs.

What ages does a Merino Kids Baby Sleep Bag fit?

It comes in two sizes - baby (0 - 2 years) and toddler (2 - 4+ years).

How do I put on my Merino Kids Baby Sleep Bag?

Simply unzip the bag, undo the shoulder domes, and lay baby on top of bag. Insert arm through armhole, and dome up the second shoulder. Zip bag up, and ensure that baby is sitting comfortably inside the bag before laying baby to sleep.

How do I dress my child when they are in their Merino Kids Baby Sleep Bag?

The Merino Kids Baby Sleep Bag is your ideal all-year-round baby sleep bag, perfect for nursery room temperatures from 64°F to 75°F (18°C to 24°C). Most rooms rise and fall in temperature throughout the night and day, and the natural merino fiber has the remarkable ability to maintain your baby's warmth without overheating. Simply dress your baby in more or fewer layers of natural-fabric sleepwear in cooler or warmer seasons.

For cooler rooms or during the winter season, we recommend the Merino Kids winter-weight sleep bags, which have an additional layer of natural insulation and will keep your baby warm in room temperatures from 59°F to 68°F (15°C to 20°C). Merino Kids winter-weight sleeping bags are available in both our usual sizes, for babies up to two years old and for toddlers aged two to four years old.

What other bedding do I use with my Merino Kids Baby Sleep Bag?

Use only a flat or fitted bottom sheet on the bassinet/cot/bed and place your baby in the Merino Kids Baby Sleep Bag. This will prevent them waking up, getting out or tangled up in bedding. It is not necessary to use blankets, top sheets or duvets when using the Merino Kids Baby Sleep Bag.

Merino Kids Baby Sleep Bags don’t have sleeves – won’t my child get cold?

This is to ensure air circulation; Babies sleeping under traditional blankets rarely sleep with their arms inside the covers. We recommend layering garments to ensure your child is perfectly adapted to their environment. The best way to measure your baby’s temperature is to check behind their neck. So long as the core temperature is okay, arms and hands can be cooler due to poor circulation in the first 12 months.

I want to put my infant into a toddler (2-4 year) bag – how big should they be for this?

We base our sizing on the 50th percentile of babies according to New Zealand Plunket guidelines. If your baby is getting too big for the baby Merino Kids Baby Sleep Bag, they may need to start sleeping in the toddler bag. The neckline and armholes are bigger in the toddler bag, so this will need to be taken into consideration when deciding which bag to use.

How do I care for my Merino Kids Baby Sleep Bag?

Merino Kids Baby Sleep Bags are extremely easy to care for. Due to the fact that Merino Kids Baby Sleep Bags are 100% natural, it is very important that you follow the washing instructions found inside the garment carefully. Click here for washing instructions.

What is a TOG rating?

The British "TOG" value is the international standard measurement of all blankets' thermal effectiveness (how well it keeps you warm). The TOG rating describes the warmth or 'Thermal Resistance' of a fabric, and is widely used in the UK to describe warmth levels of duvets and sleeping bags.

Why don’t Merino Kids Baby Sleep Bags have a TOG rating?

Because Merino Kids Baby Sleep Bags are made from 100% natural fibers, and regulate your baby’s temperature, they do not require a Tog Rating.

Safe Sleeping

What is the best room temperature for my child’s bedroom?

Between 65 and 85˙F. If lower, we recommend using the winter weight Merino Kids Baby Sleep Bag, and layering under the bag with merino garments. See our temperature guide for more details.


Why do you call Merino the 'wonder fiber'?

Merino is widely known as the wonder fiber, due to its natural abilities to regulate body temperature. It is also a miracle fiber for premature and low birth weight babies. Studies of infants at Cambridge Maternity Hospital, UK, found that those sleeping in merino settled more quickly, cried less, fed better, and gained weight faster. Merino also naturally prevents the build up of odor, so can be washed less often, and is the perfect fiber for babies with skin allergies and eczema as it won’t irritate even the most sensitive of skin.

My child has sensitive skin/allergies – would merino irritate this?

Merino is unlike traditional wool, in that each fiber has a silky outer on every strand, creating an extremely soft, fine texture. It naturally regulates body temperature and absorbs and releases moisture, eliminating dampness, which can breed germs and allergens.

How do I care for my merino products?

Always follow the care instructions on the packaging. Merino garments should be washed using wool-approved liquid only. They can be washed in a machine on the delicate cycle using luke warm water – below 104˙F. Merino garments should never be soaked, bleached, washed in hot water, soaps, or spot cleaned. Dry your garments flat in the shade away from direct sunlight. You may tumble dry on a low heat, and iron with a cool setting. Click here for more details.

Isn’t Merino too hot for warm temperatures?

Merino naturally regulates body temperature. It breathes, and removes any moisture away from your baby’s skin, releasing it into the atmosphere. Synthetic fibers do not have this ability, and trap moisture next to baby’s skin, creating a chill zone. See our temperature guide
