What is an effective preventive measure against cot death?

Placing babies on their backs to sleep is recommended as a highly effective preventive measure against sudden infant death syndrome (SIDS), commonly referred to as cot death. This sleeping position significantly reduces the risk of SIDS, as it helps to maintain an open airway and prevents the infant from rebreathing exhaled carbon dioxide that may occur with certain sleeping positions or bedding arrangements.

Research, particularly from campaigns such as the "Back to Sleep" initiative, has strongly supported this practice, demonstrating a notable decrease in SIDS cases since its implementation. The back-sleeping position encourages safer sleep and has become a standard guideline in pediatric recommendations regarding infant care.

On the other hand, the other options do not align with safe sleeping practices and can contribute to an increased risk of SIDS. Soft bedding and co-sleeping with parents can pose suffocation hazards, while placing a baby on their tummy for sleep is discouraged due to its association with greater risks of SIDS.
