Baby TOG and room temperature checker
By BabyNido editorial team · Published · Last updated
A room reading cannot determine one safe TOG or outfit for every baby. This checker explains what to consider; use your specific sleeping bag’s instructions. Read sleeping bags and TOG.
How should you use a room reading to choose a TOG?
Use the room reading alongside the instructions for your exact sleeping bag. The Lullaby Trust recommends a room temperature of 16–20°C, but does not publish one universal TOG and clothing chart. Products and babies differ. Check your baby’s chest or neck and avoid overheating rather than treating a calculator as a prescription.
| Room | Context | Next step |
|---|---|---|
| Below 16°C | Cooler than the recommended room range | Check the exact bag maker’s chart and seek advice if your home is difficult to keep warm. |
| 16–20°C | Within the recommended room range | Use the maker’s clothing guidance for this bag; check your baby rather than relying only on the number. |
| Above 20°C | Warmer than the recommended room range | Review clothing and bedding, avoid overheating and follow the bag maker’s warmer-room instructions. |
