Merino for Babies and Children - The Sleep Store Guide

What is Merino Wool?

Merino wool is a natural wool fibre that comes from Merino sheep. Known, for it's softness and versatility, merino wool is nature's wonder fibre. It's grown year-round using sustainable farming practices and has a very light environmental footprint, especially when compared with synthetics. All it takes is sun, water, air and grass to grow new merino wool every year.

Merino wool is measured in microns and is divided into categories which can determine the quality and use of the wool. (Thanks to Woolmark.com) At The Sleep Store, our styles range between 18.5 microns to 21 microns. All our Merino styles are accredited by Woolmark.


What is a micron of wool?

Merino wool is measured in microns, which is the diameter of the merino fibre. The lower the micron, the finer the merino wool. Our own brand The Sleep Store Merino clothing & sleepwear styles range between 18.5 microns and 21 microns and styles are accredited by Woolmark. Our Basics range of merino is 21 microns with our premium midweight Merino made from 19.5 micron Merino wool, which is known as "extra-fine". Check the product page for your preferred style to confirm the microns of each garment.


What makes Merino wool so wonderful?

Here at The Sleep Store, we believe using breathable, naturally temperature-regulating clothing and bedding for your children is best and Merino wool is the perfect fibre to achieve this. Recent research also suggests that babies sleep better in wool and Merino Wool in particular is a bit of a wonder fibre! Here are just some reasons why merino wool is so wonderful:

  • Breathable & temperature regulating
  • Moisture wicking
  • Renewable
  • Easy care
  • Long lasting & sustainable

Why is Merino wool so popular?

Merino wool has the same qualities as wool - but supercharged! Merino wool fibre is much finer than ordinary wool, it's silky soft, so it doesn’t itch; it’s lightweight, resists odour and is snuggly warm but never too hot because it's breathable. It really is the ultimate fibre for being next to your child’s skin (Mums and Dads like it too!). On top of this, it's easy-care, long-lasting and sustainable and who doesn't want to be kinder to our planet?

With Merino wool, you get what you pay for. The best brands use high-quality superfine Merino wool fibres. They are softer, warmer, less bulky and more durable. Looked after properly, your Sleep Store brand and Woolbabe garments will last for years and several children, so they're a good investment.


Is Merino wool safe for babies?

Merino wool is a natural fibre and perfect for babies in so many ways. It's breathable and can absorb up to 35% of its own weight in water, meaning your baby won't be clammy or overheat - they'll be just the right temperature. Merino wool will also remain warm when wet, so if there’s an overnight leak, having a Merino wool layer next to the skin can help keep your baby warm as it wicks the moisture away. Merino wool is also resistant to mould, mildew and bacteria, which helps create a healthy sleeping environment.

Merino Wool has a higher ignition point than synthetic fibres, making Merino wool an ideal choice for babies. Due to its higher water content, Merino wool is slower to ignite and won't melt like synthetic fibres such as polyester or nylon. This means it will not do as much damage to the skin as a synthetic fibre. It's an ideal layer for babies to wear next to the skin.


What's the difference between The Sleep Store Merino wool styles?

We offer a range of different Merino wool weights and styles. Here are the main differences:

Basics Merino
This is our best value 100% Merino Wool.  Available in two popular base layer options only – singlet suits and bodysuits, sold separately or as a multipack. It is available in cream so it can be easily layered.  At 190gsm the Basics Merino is the lightest weight of our 100% merino wool offerings but not as fine (or silky smooth to touch) as our Deluxe Rib or Jersey Merino.  It is an affordable and durable option.

All Seasons Merino Tencel
This is an everyday collection made from 70% Jersey Merino Wool / 30% Tencel. The jersey blend fabric has a silky, cool feel, and is the lightest Merino wool blend option at 165gsm. The Tencel makes it great for wearing all year round and ideal for sensitive skin.  Available in a range of baby, children and adult styles. 

Jersey Merino
Made from 100% New Zealand merino wool, our Jersey Merino Wool  range is super smooth and soft. It feels like high-quality t-shirt fabric and has a comfortable stretch - not as much as the Deluxe Merino rib. Great for layering all year round at 200gsm. Garments can be worn as day or nightwear and the range also includes mix/match separates.

Deluxe Merino Rib
Made from 100% New Zealand Merino Wool, this range uses a rib knit merino wool, meaning its structure consists of rows of stitching. This gives this merino wool a beautiful stretch with cross-grain elasticity. It is so soft and great all year round at 220gsm. This is our super popular merino wool range, which we've now made for 10 years, available in base layers & swaddle blankets.

Fleece Merino Tencel
Super warm at 270gsm, our Merino Tencel Fleece range is ideal for cold nights and wintry days.  Made from a blend of 68% Merino Wool, 29% Tencel and 3% Elastane, this range is super soft and fluffy on the inside with a sweatshirt feel on the outside. The items in this range can be used for day or night wear and includes children's onesies, joggers & jumpers as well as women's jumpers, breastfeeding jumper, pants and blanket options.  

Premium Midweight Merino
This is a beautiful soft and thick 100% Merino Wool interlock which allows for comfortable stretch whilst retaining shape.  A lovely warm option, at 250gsm it is our warmest 100% Merino Wool option.  This is our only 100% Merino range that is available in prints.  Styles in this range include in premium pyjamas,  zipsuits and sleeping bags. 

Merino Knitwear
Crafted from 100% Merino Wool. Designed for daywear, the easy-care machine washable Merino Wool knitwear range is available in a range of stylish garments to keep your little ones warm.


What's ideal nursery temperature?

The ideal temperature for a child’s room is between 18-20 degrees. While this may feel a little chilly to you, your littlies will sleep better in a cooler room with warm layers close to the body. Rooms should be kept above 18 degrees to help prevent respiratory problems.

The temperature dips in the early hours, so if your little one starts to wake around 5am then he is probably having a hard job getting back to sleep because of the cold. Using the right weight sleeping bag, wool bedding and Merino wool layers can really help you both get a great night’s sleep. And don’t forget socks! We have lots of feedback from customers for whom adding a pair of Woolbabe Sleepy Socks has meant their baby sleeps through again.


Watch Lou talk about merino and its benefits for your baby

We love merino wool at The Sleep Store. What is so wonderful about this fabric? Why is it so helpful in allowing your baby or child to sleep longer and easier? Did you even know it's fire-resistant?


How do I care for my Merino wool?

Because merino wool is odour and bacteria-resistant it doesn’t need to be washed too often; just when it looks grubby. Sleeping bags like a good air over the cot bars in the day. You can handwash or use the gentle wool cycle in your washing machine - check the washing instructions on your garment.

Traditional detergents, soakers or bleaches will eat holes in your Merino wool garments. Always use an approved wool detergent like the Ecostore wool wash. Merino wool dries really fast in the shade and some types of merino wool can even go in the dryer on low - see the garment’s care instructions for details.

Please take care to avoid moths when you store your Merino wool garments. We highly recommend cedar wood balls and Lavendar as natural ways to keep moths at bay. The simple habit of keeping wardrobe doors and drawers closed can reduce moths getting into cupboards to begin with.

Taking care of your Merino wool garments will ensure it easily lasts for multiple babies.


How often do I need to wash Merino wool garments?

As parents, we have enough washing as it is! One of the great things about Merino wool is that you don't need to wash it often. For a sleeping bag, simply airing it each day is enough (unless you've had a dreaded nappy explosion!). For clothing items, washing when soiled is enough - Merino wool is naturally resistant to soiling and odour, so can be washed less often - now that's a win!


Will Merino wool garments shrink in the wash?

To preserve your merino wool items, they should be washed on a cold gentle wool cycle and they should not be placed in a dryer as this may cause shrinkage.


Can babies wear Merino wool clothing in Summer?

Yes! Because Merino wool is so breathable it can also be cooling in the warmer months. And the fact that it can absorb up to 35% of its weight in water means it can draw sweat away from the body without making baby clammy and cold. Our lightest Merino wool styles include the Basics Merino and the All Seasons Merino/Tencel styles. These are great for layering day or night.


Is Merino wool good for kids with eczema or sensitive skin?

Most wee ones with mild to moderate eczema can wear superfine Merino wool garments comfortably. Choose The Sleep Store All Seasons or Jersey Merino styles or Woolbabe items. When my eldest was a baby, it actually helped his eczema. As an eczema baby, he tended to overheat and was grumpy and itchy if he was too hot. With a Merino wool layer next to his skin, I was confident he was warm enough without too many layers and wouldn’t overheat. If your baby suffers from severe eczema then we would recommend you use cotton or bamboo next to the skin. Tencel can be really useful for bedding. Merino wool is gentle on even the most sensitive skin.

Watch Lou discuss merino & sensitive skin:


Is Merino wool better than cotton?

Merino wool and cotton are both lovely, natural fibres for babies and we recommend parents have a mix of both items. Merino wool, however, is better at regulating babies temperature, and its high water absorption compared to its weight means it won't become damp and clammy if your baby is too hot.

Both Merino wool and cotton can be machine-washed, and Merino wool has the added benefit of resisting soiling. This means it needs to be washed less often; a simple air out can be all it needs.

If you can get just one Merino wool item, we recommend a long sleeve Merino bodysuit for its versatility - great next to the skin and can be used for layering.


Why are Merino wool items not TOG rated?

Merino wool bags are not tog-rated, as they are natural fibre which adjusts according to temperature. This is one of the reasons natural fibre Merino wool sleeping bags are so popular. Sleeping bags that have Merino wool in them, like the Woolbabe or The Sleep Store styles are fantastic at adjusting to a wider range of room temperatures.


What is Merino fleece?

Merino fleece is completely different from what you may remember as 'polar fleece' from your childhood. Merino fleece is created by brushing from 100% merino wool, to 'fluff' it up, making it extra soft and snuggly. This is miles away from polar fleece, made from synthetic material which can easily overheat your baby and should be avoided.


What is All Seasons Tencel Merino?

The Sleep Store All Seasons Tencel Merino range is 70% Merino Wool and 30% Tencel. What is Tencel? Tencel is made from regenerated wood pulp, usually Eucalyptus or Beech trees. It's super slinky and the addition of the Tencel makes it cool to the touch. The blend makes it our lightest Merino wool style and is great for sensitive skin.


Is Merino fleece different to polar fleece?

Yes! Merino fleece is made from Merino wool and is 100% natural, whereas polar fleece is made from synthetic fabric. Polar fleece doesn't breathe and can easily overheat a baby. We never recommend polar fleece for babies.
