Overheating is known to be a factor in cot death. If the room is hot for you, keep your baby's clothes or bed covering light. They get too hot. Although it is fine to take your baby into your bed for comfort, a baby falling asleep under your duvet may get too hot. Never use a hot water bottle or electric blanket.
Babies have a delicate skin, which can scald, or burn, easily.
Ill or feverish babies don't need any extra bedding. In fact they usually need less. Remove hats and extra clothing as soon as you come indoors or enter a warm car, bus or train, even if it means waking your baby. Clean air Babies shouldn't be exposed to tobacco smoke, either before birth or afterwards. If you, or anyone else who looks after your baby, smokes then don't smoke anywhere near the baby.
