The right temperature
Babies cant control their own temperature very well. Its just as important to stop your baby getting too hot as too cold, because overheating is known to be a factor in cot death. Heres how you can keep your baby just right:
* Keep the room where she sleeps at a temperature of between 16°C and 20°C (61°F and 68°F). If youre comfortable in the room wearing light clothes, its warm enough for a sleeping baby
* Dont cover your babys head when she is indoors and dont put your baby to sleep in a hat
* Its not safe to use a duvet, quilt or pillow for your baby until shes a year old; use sheets and blankets instead, that way you can add and remove layers more easily
* If the room is hot, keep her clothes or bed covering light.
* Dont put your baby to sleep in front of a fire, by a radiator or heater, or by a very sunny window
* Keep the room in which she sleeps at an even temperature so that you can put the right number of blankets on when she goes to bed and be confident that she will remain comfortably warm all night
Room temperature
The ideal room temperature for your baby is between 16°C and 20°C. Below this temperature he will be too cold and above it, he will be too hot. Room thermometers are available post-free for £2.75 from the Foundation for the Study of Infant Deaths on 0207 233 2090.
* To check if your baby is too hot, look for sweating or touch the baby; dont worry if her hands or feet feel a little cooler than her body, thats normal.
* Never use a hot water bottle or electric blanket for a baby.
* Never place babys cot near a radiator or in direct sunlight he could overheat.
