  • What is the grobag® egg™
  • grobag® egg™, the colour changing digital room thermometer is another clever innovation from the people who brought you grobag® baby sleeping bags. 
  • Room temperature is vital in creating a safe sleeping environment for your baby and should be maintained at 16-20°C to help reduce the risk of cot death. 
  • The grobag® egg™ glows yellow if the room temperature is within recommended guidelines (16-20°C). If the room temperature is outside this range, it acts as a reminder for you to take action to cool or heat the room, or to adjust the baby’s bedding or clothing. 
  • Every baby’s home should have a grobag® egg™ room thermometer and it is ideal for use with grobag® baby sleeping bags to help you to monitor the temperature of the room where you baby is sleeping. 
  • “Babies who get too hot are at an increased risk of cot death…getting a room thermometer will help you create a safer sleeping environment for your baby” Joyce Epstein, Director FSID. 
  • Key Features:
  • Simple to use room thermometer that changes colour
  • Digital room thermometer with permanent ‘back-lit’ LCD readout
  • Provides a soft and very subtle glow
  • Mains power adaptor included
  • Instructions and safe sleep guide enclosed
  • Using the gro egg
  • Your grobag® egg™ displays the exact room temperature in °C, and will display one of four colours depending on the room temperature.
  • Please see the chart below:

  • If the room temperature is outside the recommended guidelines (shown by the yellow colour) there are 3 actions you can take. 
  • 1. Cool or heat the room 
  • For example, by opening or closing a window or door or using a thermostatically controlled heater or radiator. 
  • 2. Adjust the bedding
  • Increase or reduce the amount of bedding. For example, for grobag® baby sleeping bag users choose a different tog rating. For those using traditional sheets and blankets, add or remove layers. 
  • 3. Adjust the baby's clothing 
  • Reduce or increase the number of layers of clothing your baby is wearing. 
  • Please note, always remember to check your baby to make sure he or she is not too hot or cold. To check if your baby is too hot, look for sweating or feel your baby, don’t worry if hands or feet are cold, that’s normal. If in any doubt please consult your health professional. 
  • Quick reference:
  • Use the table to help choose the level of bedding and clothing for your baby. These are recommendations only and you will soon discover the best level of clothing for your individual baby

  • Using the gro egg with blankets:
  • Please note, grobag® baby sleeping bags are designed to be used instead of blankets and sheets.
  • Never use with a duvet or quilt as this increases risk of cot death
