Is 24C OK for a baby's room?
Short answer: 24C is above the recommended 16C to 20C range. Remove a layer, use lighter bedding, keep the cot out of direct sunlight, and check your baby's chest or neck for heat or sweat.
A room thermometer is the easiest way to check.
What the guidance says
- Keep the room between about 16C and 20C and check it with a room thermometer.
- Check your baby's temperature by feeling their chest or the back of their neck. Cool hands and feet are normal.
- Never use a hot water bottle or electric blanket, and do not place the cot next to a radiator, heater or fire, or in direct sunlight.
- The Lullaby Trust does not publish a tog chart, because fabrics, layers and babies differ. Use the room temperature as a guide and check your baby's chest or neck.
