What is a TOG rating?

How to chose the right TOG or temperature rating for you baby to wear to bed.

We believe the simplest way to make sure your baby is suitably dressed is to dress for room temperature. We've create a temperature-based rating across 5 key categories to support the the process.

To best dress for different room temperatures and ensure you select the right Love to Dream product follow these three simple steps:

• Prior to selecting a Love to Dream product we would recommend having a good understanding of the temperature of your baby’s room.
• Always look for the ideal room temperature guidance on our products and website to help your selection.
• Follow the recommended clothing by room temperature within the temperature chart below.

Before there was TOG

Although TOG is a trusted system which has existed for decades, some Love to Dream products may reference an alternative temperature guide.  We know Love to Dream products are treasured and regifted again and again.  So, if your product doesn’t have a TOG guide, please use the temperature guide below.  

• Products with a Warm Rating equal a 0.2 TOG and are ideal for Room Temperatures from 24-27°C.  
• Products with a Moderate Rating equal a 1.0 TOG and are ideal for Room Temperatures from 20-24°C.  
• Products with a Mild Rating equal a 1.5 TOG and are ideal for Room Temperatures between 18-24°C.  
• Products with a Cool Rating equals a 2.5 TOG and are ideal for Room Temperatures between 16-20°C.
• Products with a Cold Rating equal a 3.5 TOG and are ideal for Room Temperatures below 16°C.  

How to use our TOG temperature chart

To choose the right product for your child, follow these 3 simple steps:

• Determine the temperature or the room your baby will be sleeping in
• Use our TOG guide to determine the matching rating (for example: if your baby sleeps in a ~20C room the ideal TOG is 1.0 TOG.
• Depending on the room temperature, your baby’s health and their physiology you then decide on the number of layers to wear underneath the sleep garment. (In the above a example the ideal combination could be long-sleeved pyjamas and a sleeveless bodysuit).

How should I consider TOG when dressing my child?

Published TOG ratings (with appropriate rounding) should be considered in conjunction with our specific clothing guides (found online and on pack) and are from test results that we believe reflect the appropriate TOG when used in conjunction with our clothing guides. Test methods are EN ISO 11092, ASTM 1291(modified to the same parameters as EN ISO 11092) and ISO 5085-1. 

We believe that our TOG ratings, together with our clothing guides, help parents and carers make the best decision on how to dress their child at different room temperatures. We also provide guidance on how the parent or carer can check if the child is too hot or too cold. This is important in empowering the parent or carer to decide what is best for their child. All children are different. The number of clothing layers required may vary according to a child’s health, their physiology the room temperature, the outside temperature and other factors. The care-giver must determine what is suitable. We do not provide medical advice. 

The TOG rating (with appropriate rounding) is obtained using any one, or combination, of the below globally recognised test methods, EN ISO 11092, ASTM 1291(modified to the same parameters as EN ISO 11092) and ISO 5085-1.

Common FAQs on dressing your baby for sleep

What temperature should your baby be at night?

The Lullaby Trust recommends:

• Optimal Temperature: Keep the room temperature between 16-20°C to reduce the risk of SIDS.
• Use a Thermometer: Employ a room thermometer for accurate measurement.
• Monitor Baby's Temperature: Check the baby's chest or back of the neck to ensure they are not too hot or cold.
• Appropriate Bedding: Use light bedding or a lightweight, well-fitting sleep bag; avoid hats and heavy blankets indoors.
• Adjust for Seasons: In warmer weather, use lighter bedding and ensure good ventilation; in cooler weather, add layers as needed but avoid overheating.

Can I layer sleep bags to increase the warmth?

It’s not recommended that you layer sleep bags or swaddles, as this can increase the risk of overheating or suffocation. Instead, choose an appropriate garment for the room temperature and select lightweight layers that can be worn beneath.
