Take the guess work out of dressing your little one for bed - the temperature regulating Merino Wool does all the hard work for you keeping your baby warm when it's cold and cool when it's hot.  Our clever sizing grows with your baby, making our Merino Baby Sleeping Bag a cost effective investment for your little one's sleep.  If you use regular TOG rated sleeping bags you will need to buy multiple sleeping bags to cover all the different sizes and temperature ranges which are covered by just ONE of ours!

All our products are proudly Australian Made.

Designed with safe sleep in mind, features include:

  • Superfine Australian Merino Wool lining keeping your little one at a safe, regulated temperature 
  • Premium 100% Linen outer - pre-washed for a textured yet luxuriously soft feeling
  • Suitable for temperature range: 18 - 28°C. View temperature guide for how to layer underneath
  • BABY size recommended from 3-24 months.  Also available in TODDLER size.  View size guide
  • Research has shown that superfine Merino wool encourages a deeper, more restful sleep and improves eczema symptoms
  • Handy underarm poppers to adjust the size as your little one grows 
  • Durable YKK zip opens from the underarm for easy dressing and nappy changes
  • Safe sleep - use without any additional bedding
  • Merino Wool is naturally flame resistant therefore we don’t need to apply chemical flame retardants
  • Also available in our baby sleeping bag value set and Mum & baby gift set with matching linen robe for mama 
  • Easy care - Machine washable
  • Buying as a gift?  Add a signature Billie + Bobbie gift box with our compliments - just check the tick box at cart


NOTE: We recommend NOT to use the underarm snaps for babies above 5kg as they are safely over the minimum weight - due to the delicate nature of the merino wool it can be damaged if put under excessive pressure.  You should be able to comfortably slide your hand between the sleeping bag and your baby.

    Safety Standards & Features

    - Fitted around the neck to prevent the baby’s face being covered while sleeping
    - Bell-shaped bottom to promote healthy hip joint development as recommended by the International Hip Dysplasia Institute
    - Compliant to Australian standards AS/NZS 1249:2014 for children’s nightwear
    - Sleeveless design and breathable natural fibres help to prevent overheating

    Size Guide

    Our merino sleeping bags come in 2 different sizes and our clever adjustable sizing means each sleeping bag should last you around 2 years!


    Approx age

    Chest (at armhole)

    Length (from side neck)





    Toddler 2-4yrs 38cm 107cm

    The minimum weight recommended for sleeping bags is 4.5kg.

    You will most likely transition to this bag once your baby starts rolling and they are no longer swaddled.  It is important to have a snug fit around the neck.  You may notice that the armholes come slightly lower than other brands which is due to our clever adjustable sizing but your little one will still be kept warm and snug.  

    Temperature Guide

    Follow this handy 2 step guide to ensure your little one remains the ideal temperature all night long:

    Step 1 – determine the temperature of your baby’s sleeping environment.  This may vary from day to night, and factor in that the temperature drops during the night

    Step 2 – use the guide shown below to match the room temperature with the number of layers to dress your baby in underneath their swaddle/sleeping bag.  It’s that simple – the Merino Wool has taken the hard work out of it for you!

    To check, feel baby’s tummy, which should feel warm.  Don’t worry if baby’s hands and feet feel cool – this is normal.  Dress your baby as you would dress yourself for the temperature of the room – comfortably warm, not too hot, not too cold.

    Billie and Bobbie sleeping bags have a temperature range rather than a TOG rating due to the temperature-regulating properties of Merino Wool. There are a number of factors that should be considered when determining which sleeping bag you should use for your baby such as the clothing your baby is wearing underneath the sleeping bag, the room temperature, and your baby’s health.  The requirements may vary from child to child but this information is provided as a guide.

    Cosiness to last for years

    I was so excited to try this out when my little one outgrew being swaddled, the fabric feels such lovely quality and she looks so cosy in it! She's 6 months now and there's still plenty of room left to grow. Definitely worth the investment as it has saved me having to buy lots of different sizes and togs. One of my favourite baby purchases!

    We have the winter and all season, this is beautiful for when we sometimes bring bub into our bed in the early morning in Melbourne winter, gorgeous fabrics, and no yucky Tog system.

    Amazing sleeping bag!

    I'm obsessed with this sleeping bag! After trying out heaps of other brands this is by far the best. The breathable natural fibres mean I don't worry about our little girl overheating or waking up clammy and sweaty. It feels so nice and soft. Absolutely worth the money.

    Beautiful Sleeping Bag

    The quality of this sleeping bag is incredible. I’m so happy I purchased, it’s definitely worth paying that little extra for! I went for the all season to make the most for the price as we live in a warmer climate and although I was concerned it was a little thin to keep my daughter warm, she sleeps so well! I would still love the winter option for nights below 20 degrees so she only needs to wear the one layer. The temperature guide is perfect for dressing too!



    Hi Chelsey, Thank you for taking the time to leave such a beautiful review. We love hearing that your daughter sleeps well in her Billie + Bobbie! B+B x

    Love love love

    Ordering right through to our sleeping bag arriving was a dream! Our 6mth old absolutely loves her sleeping bag! Won’t sleep in her previous bags at all now! It also gives me so much comfort that she is sleeping in such a quality product that can be worn in all seasons. The fact she will fit in this for a long time before we need to buy another is a huge bonus!



    Hi Kate, Thank you for the lovely feedback! We are so happy to hear that your little girl loves her sleeping bag! B + B x
