What is Tog Baby?

Published in Baby Sleep Safety 2 mins read

The question "What is Tog baby?" is a little unclear. A more accurate phrasing would be: What is a TOG rating in the context of baby sleepwear and bedding? This refers to the Thermal Overall Grade (TOG) system used to measure the warmth and insulation of these items.

Understanding TOG Ratings

TOG, which stands for 'Thermal Overall Grade,' is a unit of measurement that indicates how well a fabric insulates. It's commonly used in sleepwear and bedding, especially for babies, to help parents choose appropriate clothing and bedding to keep their child comfortable and safe during sleep.

  • What it measures: Insulation and warmth of sleepwear and bedding.

  • How it works:

    • Lower TOG rating = Lighter fabric (suitable for warmer temperatures).
    • Higher TOG rating = More padded and insulated fabric (suitable for colder temperatures).

ergoPouch, for instance, uses TOG ratings in their range of pouches and pyjamas to help parents select the right level of warmth for their baby, as referenced.

Practical Application of TOG Ratings

Using TOG-rated sleepwear and bedding can help reduce the risk of overheating, which is a concern for infants. Here's a table illustrating general guidelines for TOG ratings and corresponding room temperatures:

TOG Rating Room Temperature Recommended Use
0.2-0.5 24-27°C (75-81°F) Lightweight sleep sack or swaddle for warm weather
1.0 20-24°C (68-75°F) Lightweight sleep sack or swaddle for mild weather
2.5 16-20°C (61-68°F) Sleep sack or swaddle for cool weather
3.5 Below 16°C (Below 61°F) Warmest sleep sack for cold weather

Example:

If a baby's room is 22°C (72°F), a sleep sack with a TOG rating of 1.0 would be a suitable choice.

Benefits of Using TOG-Rated Products:

  • Safety: Helps prevent overheating, reducing the risk of SIDS (Sudden Infant Death Syndrome).
  • Comfort: Ensures the baby is neither too hot nor too cold, promoting better sleep.
  • Convenience: Provides a clear and standardized way to choose appropriate sleepwear and bedding.
