Sleeping Bag For Babies - The Only Buying Guide You Need To Read

With the vast amounts of sleeping bags for babies available on the market, it can be daunting when it comes to deciding which is best for your baby.

Here, we will make a list of things to look for that will help make your decision-making process easier.

Sleeping bags come in a variety of sizes.

For example, 0-3 months, 3-6 months, 6 months - 2 years, etc.

The sleeping bag should be large enough for your baby to kick and wiggle freely.

Another bonus of that is it can be used for an extended period of time, usually for about 1 to 2 years, or more.

For safety purposes, ensure that your baby's head is not able to easily fit through the head opening to reduce the risk of submarining, which can lead to suffocation.


Some sleeping bags come with arm holes snap buttons.

This helps to give a snug fit for babies who are in the lower age range.

A sleeping bag doesn't necessarily need to have one as long as the arm holes are small enough for a snug fit. This helps keep your baby warm, and helps prevent your baby from getting his/her arms into the sleeping bag.

It is important that your sleeping bag uses natural fibers, such as cotton, merino, or cashmere. This is because natural fibers are breathable, which helps reduce sweating and prevent overheating for a comfortable sleep.

  • Cotton - soft, warm, breathable, durable. Good for babies with wool allergy. Able to be machine-washed or tumble-dried.

  • Merino - softer, warmer, more breathable than cotton, but less durable. Hand wash in cold to lukewarm water or machine-wash on delicate setting in mesh bag, and can't be tumble-dried.

  • Cashmere - luxuriously soft, up to 8x warmer than merino, highly breathable, but less durable than merino. Hand wash in cold or lukewarm water or machine-wash  on a delicate setting in a mesh bag, and can't be tumble-dried.

Synthetic fibers like polyester are not breathable and are not able to draw moisture away from your baby's body. This makes it much more likely for your baby to overheat.

Tog Rating

Tog (Thermal Overall Grade) rating is used as an indication of the warmth of a sleeping bag.

It is merely a guide and not a safety standard.

The higher the tog rating, the warmer it is.

Cotton sleeping bags almost always have a tog rating.

However, it is common for merino or cashmere sleeping bags to not have a tog rating. This is because merino and especially cashmere, are highly breathable with exceptional temperature regulation. As a result, they're able to be used in a wide temperature range which doesn't fit into the general tog rating recommendations.

As a general guide:

TOG rating and clothing guide

Sleeping bags usually come with a temperature guide specific to the one that you bought.

It outlines a recommendation for the clothing that you should put on your baby when using the sleeping bag at a particular room temperature. For example, this is the temperature guide for our Snurfle Cashmere baby sleeping bag:

Please note that these are merely recommendations as every baby is different. You may need to monitor your baby's temperature in the beginning to find the best option for your baby. The best way is to check the warmth of the back of your baby's neck.

A Final Tip

We highly recommend getting at least two sleeping bags for your baby.

It is inevitable that your baby will have a leak in the middle of the night at some point. The last thing you want is to not have a fresh, clean sleeping bag on-hand to put your baby into.

With that, we hope you have enough information to find the right sleeping bag for your baby.
