Tog rating and room temperature

Everything your baby wears has a TOG rating. Want to know which grobag to put your little one in? I always recommend using sleeping bags as you can be sure it is the perfect tog value for the temperature of the room and the clothes your baby is wearing. Check tog ratings of nappies, clothes and sleepsuits and find other important bed time related info here:

What is the ideal temperature for my baby’s bedroom?

18C is the ideal temperature for your child’s bedroom. A reliable thermometer should be placed in his bed or as close to his bed as possible as temperatures can vary in different areas of the house. Compare the best baby room thermometers.

  • Avoid having your heating on during the night except when it is very cold weather.
  • If your heating is on it should be controlled by a thermostat to ensure a constant temperature.
  • Never allow your child to sleep next to a radiator, heater, fire or in direct sunlight.
  • Never give children hot water bottles or electric blankets.
  • Always be aware your newborn could overheat if he is wearing too much clothing or has too much bedding.

What are the TOG values of baby clothes?

The list below should be used as a guide only. The best way to test if your little one feels hot is to touch his tummy before you put him to bed to see how he feels, you can do this again at varying points during the night (when you wake up/when he wakes up/ when he needs feeding etc.) The estimated values are as follows:

What should my baby wear to bed?

The safest and easiest way to judge this is firstly checking the temperature of the room (using a thermometer) and adding enough layers to make it up to the TOG value required. The values are:

  • 12-14 when the room is 16 degrees Celsius
  • 10-12 when 18 degrees Celsius
  • 08-10 when 21 degrees Celsius

If the temperature is between 19-21c the following baby clothes would be suitable – Nappy, sleep suit, baby grow and a 2.5 tog sleeping bag.
If you expect it to get extremely cold during the night, it is OK to set the heating to come on as long as it is:

  • Thermostatically controlled and the thermostat is set at no more than the recommended room temperatures (as above) and
  • Your child is dressed appropriately for this temperature.

I would recommend using a digital thermometer if you are going to do this as some centrally heated rooms heat up quicker and get hotter than others, using a grobag or something similar guarantees your bedding is just right. If have your little one in bed with you during the night then you need to ensure you create a safe co-sleeping environment.

How do you judge what to put your baby in at bedtime? Do you regularly worry that the room is too hot or too cold?

  1. Can anyone tell me the tog rating on wadding ? I want to make baby sleeping bags but I am not sure what thickness of wadding to use. Wadding comes in oz and not togs.

  2. I used sleeping bags on my baby but only after he was about 5 weeks old. In this heat I don’t even bother checking the room temperature coz I know its too hot for any kind of blanket. In the winter I always check as don’t want him waking up coz he’s cold.
