It can be a struggle to keep your baby comfortable at night time, there is no doubt that if your child is kept at the right temperature, it will have a positive effect on the quality of their sleep. Below are some tips that may help.

Consider the room in which your child sleeps. The recommended room temperature for a baby is 16-20 degrees. For many of us, this feels a bit chilly, but research has shown that it is a safe and comfortable temperature for a baby to sleep in.

However, we know in an ideal world this can be a little tricky to achieve. This guide will help you navigate this tricky area with a little more ease, it can be as simple as adjusting the temperature in the room if you have the ability or dressing your baby according to the temperature.



The Groegg is a great help when it comes to showing at a glance whether the room temperature or your child’s sleep attire needs adjusting.

The colour of the glow matches back to our Grobag tog rating system, Blue is 3.5tog, Yellow is a 2.5 tog, Orange is a 1.0 tog and Red is either a 0.5 or 0.2 tog.



Your baby’s bedding is important, and you should choose it with care. Grobags are ideal, as they keep your child cosy and replace the need for sheets and blankets, which can be kicked off or pose a threat to baby’s safety.



Grobags are available in 5 different tog values (level of thickness/warmth of the bag), so you can keep your baby comfortable in both summer and winter.

As our climate varies in each state, your most common used tog rating could be different, however our most popular tends to be the 2.5 tog as you can layer up or down under this Grobag to achieve a varying level of warmth.


0.2 tog temperatures between 27°C and above

0.5 tog temperatures between 24-27°C

1.0 tog temperatures between 21-23°C

2.5 tog temperatures between 16-20°C

3.5 tog temperatures between 16°C and below


In colder temperatures baby’s arms can feel cool compared to the rest of baby’s bodies. The Grosuit has been introduced to our range and features in our what to wear guide.

It features a single layer 100% jersey cotton body (as this is the area we are layering with the Grobag) and quilted sleeves with cuffs that extend to cover the hand to keep baby’s arms snug at night whilst still allowing adequate air to expel from the hands.


What to wear guide

The table below gives you a guide on how to dress baby depending on the temperature. We advise layering under the Grobag for safety reason. Choose your temperature than match this to the tog rating of your grobag you are using to find out what layers to wear under the grobag.

Remember this is just a guide, feel your baby’s tummy or the back of their neck (your baby’s hands and feet will usually be cooler, which is normal).

If your baby’s skin is hot or sweaty, remove one or more layers of bedclothes or bedding. It’s common to think that you need to wrap unwell babies up warmer but babies who are unwell need fewer, not more bedclothes.



If you are buying now in anticipation of the cold weather, do make sure that you get the right size. If you over estimate how fast your baby will grow, and get one that is too big, you can run the risk of them slipping down into the bag.


Whichever temperature your child is sleeping in and whichever tog you use it is important that you should never use a duvet or quilt with a Grobag and in fact even without one, duvets are not recommended for babies under the age of one year.


Remember that the safest place for your baby to sleep is in the same room with you for the first six months – this will be especially helpful in judging the temperature they will be sleeping at.


Younger babies often love to be swaddled to keep them cosy, warm, and feeling secure.  Swaddling is safe, provided that you do it from early on in your baby’s life and that a light, natural material is used such as the 100% jersey cotton that the Groswaddle is made from. Your baby’s head should be uncovered and if it is very cold in your baby’s room then increase the number of layers underneath the swaddle instead of adding other bedding on top of it.


Sometimes, despite taking every care, you might not be sure whether your baby is too hot or too cold. The best way to check is to feel their tummy or neck. Remember that babies’ hands and feet do feel cold and are not a good indication of their actual body temperature.


Remember too that new babies are not able to regulate their body temperature by sweating of shivering, so you need to make sure that they are kept safe and comfortable.
