The Baby Caterpillar Sizing:

We believe that your toddler shouldn’t outgrow their sleeping bag before they no longer need it.  With that in mind our sleeping bags come in two sizes: Newborn to 9mths this is ideal for a baby that might not like to be swaddled or wrapped, and is very popular for baby gifts.  We also have our popular 3mths to 3yrs, which is the perfect transition for any baby moving on from swaddling/wrapping.  Both size options are generous in length to allow for taller babies to have more wriggle room, and usually means they will fit for longer.   


  • Newborn to 9mths measures 85cm from the shoulder to the bottom of the sleeping bag
  • 3mths to 3yrs measures 110cm from the shoulder to the bottom of the sleeping bag - click here to buy the bigger size

  • Reinforced shoulders for maximum strength and durability 
  • Generous arm holes for temperature control and air circulation

Why Winter Weight?

The WINTER weight sleeping bags are designed for the coolest months of the year and as a guideline would be similar to wearing a sheet and two thick blankets.  With clothing alternations this sleeping bag can safety be used in temperatures below 18 degrees. 

  • The merino:-  Each of our sleeping bags has a soft layer of pure NZ Made merino against your babies skin to help absorb and release moisture and trap or circulate air as needed to regulate the temperature.
  • The cotton:-  Rather than using padding to achieve warmth, we use 100% thick, soft brushed cotton for the outer layer.

Fire requirements

Our sleeping bags have been tested and are rated as LOW FIRE DANGER.  However, all fabric are flammable, so it is recommended to stay at least 1 meter away from open fire or gas.  We DO NOT recommend walking around in your sleeping bag for any reason.

Why Merino?

We only use 100% New Zealand made super soft merino which used against your babies skin will help absorb and release moisture and trap or circulate air as needed to regulate the temperature.  Merino will keep your baby warm in winter and cool in the summertime.  Merino is an ideal fabric to use if you suffer from skin sensitivity and because it is natural it is the perfect loving touch. 

CAUTION - keep away from heat and flame

  • I have used several different types of swaddles (or wraps as you call them) over the course of my 3 children, but I just had to email you and let you know that I love your one the most.  It really is so easy to use and fits for much longer than the other merino ones I had.  I have finished having children now, but I will be telling anyone who needs a swaddle for a baby to buy your ones.

  • Thank you for my sleep. I LOVE YOU! I received one of your baby merino swaddles for a baby shower gift, and finally my beautiful baby girl slept through for more than 2 hours at night. I had always wrapped her, but she always managed to get her arms and legs out and then wake up. Having the pocket thing meant she could not get her legs and feet out, then I just had to wrap her arms, and she stayed like that all night long. I will be getting a sleeping bag very soon
