Find the Right Sleeping Bag for Your Little One

Our collection of baby and toddler sleeping bags brings together comfortable sleepwear for different ages, seasons and bedroom temperatures. From your baby's first sleep bag through to larger toddler sizes, choose from soft, breathable fabrics and a growing selection of trusted nursery brands.

Baby & Toddler Sleeping Bags

Choosing the correct size is important when buying a sleeping bag. Baby sleeping bags are designed specifically for younger babies, while toddler sleeping bags provide the additional length and room needed as your little one grows.

Always check the individual manufacturer's age, height and weight recommendations to ensure you choose the correct fit.

Choosing the Right TOG

Sleeping bags are available in different TOG ratings, which indicate their level of thermal insulation. The right TOG should be selected according to the temperature of your child's bedroom rather than simply the season.

As a general guide:

  • 0.5 TOG – for particularly warm rooms
  • 1.0 TOG – for warmer bedroom temperatures
  • 2.5 TOG – for cooler rooms, commonly around 16–20°C

Always follow the specific temperature and clothing guidance provided by the sleeping bag manufacturer.

Cotton & Muslin Sleeping Bags

Our range includes beautifully soft cotton and muslin sleeping bags designed with comfort and breathability in mind.

Cotton is naturally soft and breathable, making it a popular choice for baby and toddler sleepwear, while muslin provides a lightweight woven texture that feels gentle against delicate skin. Double-muslin designs can offer additional warmth while retaining the breathable qualities of cotton.

Sleeping Bags for Every Season

From lightweight summer sleeping bags to warmer 2.5 TOG sleeping bags for cooler nights, having different options makes it easier to adapt your child's sleepwear as bedroom temperatures change throughout the year.

FAQ's - Baby & Toddler Sleeping Bags

What is a baby or toddler sleeping bag?

A sleeping bag is a wearable form of bedding designed specifically for sleep. Rather than using loose blankets, your baby or toddler wears the appropriately sized sleeping bag over their nightwear.

What's the difference between a baby and toddler sleeping bag?

The main difference is size and fit.

Baby sleeping bags are proportioned for younger babies, with appropriately sized neck and arm openings. Toddler sleeping bags provide additional length and room for older children.

Always use the manufacturer's measurements rather than simply choosing according to age.

What TOG sleeping bag should I choose?

The appropriate TOG depends primarily on the temperature of the bedroom.

As a general guide:

  • 0.5 TOG: warmer rooms and hot weather
  • 1.0 TOG: warmer bedroom temperatures
  • 2.5 TOG: cooler rooms, commonly around 16–20°C

Always follow the individual manufacturer's temperature guidance.

What does TOG mean on a sleeping bag?

TOG is a measure of thermal insulation. A higher TOG sleeping bag provides more insulation than a lower TOG design.

This allows parents to select sleeping bags appropriate for different bedroom temperatures.

Is 2.5 TOG suitable for winter?

A 2.5 TOG sleeping bag is commonly used during cooler weather and is often recommended by manufacturers for bedrooms around 16–20°C.

However, room temperature rather than the season should determine which TOG you choose.

Do sleeping bags come in different sizes?

Yes. Sleeping bags are available in different sizes covering babies, toddlers and, with some brands, older children.

Sizing can be based on age, weight, height or a combination of measurements, so always check the manufacturer's sizing guide.

Can newborn babies use sleeping bags?

Some sleeping bags are specifically designed for newborns and young babies.

Always check the manufacturer's minimum weight or height requirements and make sure the neck and arm openings fit correctly before use.

How should a baby sleeping bag fit?

A baby sleeping bag should fit securely around the neck and shoulders so that your baby's head cannot slip down inside.

There should still be sufficient space through the lower part of the sleeping bag for comfortable movement.

What should my child wear underneath a sleeping bag?

This depends on the room temperature and TOG rating of the sleeping bag.

Follow the manufacturer's clothing guidance for the individual product and adjust clothing according to the actual bedroom temperature.

Does my baby need a blanket with a sleeping bag?

Additional blankets should generally not be necessary when your baby is wearing an appropriately rated sleeping bag.

Follow safer-sleep guidance and the instructions supplied with your chosen sleeping bag.

Are cotton sleeping bags breathable?

Cotton is naturally breathable and is widely used for baby and toddler sleepwear.

The overall warmth of a sleeping bag will also depend on its construction, layers and TOG rating.

Are muslin sleeping bags suitable for babies?

Yes, provided the individual sleeping bag is designed for your baby's age and measurements.

Cotton muslin is popular for baby textiles because of its soft and breathable construction.

How many sleeping bags do I need?

Many parents find having at least two sleeping bags in the appropriate size and TOG convenient, allowing one to be worn while the other is being washed.

Different TOG ratings can also be useful as bedroom temperatures change throughout the year.
