P. SIDS more in winter

 Ah! You mean SIDS – Sudden Infant Death Syndrome. Thanks for clarifying.


To answer your question: SIDS is somewhat more common in winter. Here’s why:


  1. Respiratory infections: Winter months see more colds and viral infections, which can increase an infant’s risk.
  2. Overheating: Parents tend to bundle babies in heavy blankets or sleepwear in winter, which can increase SIDS risk.
  3. Indoor sleeping: Babies spend more time indoors in enclosed spaces during winter, sometimes leading to unsafe sleep environments.



However, SIDS can occur any time of year, so while there’s a slight seasonal uptick in colder months in some studies, the main risk factors remain:


  • Placing babies to sleep on their stomachs or sides
  • Soft bedding or loose blankets in the crib
  • Exposure to smoke
  • Overheating



The safest practice is the “Back to Sleep” rule: always put babies to sleep on their backs, on a firm mattress, without loose bedding.


If you want, I can also explain why winter specifically affects SIDS risk physiologically—it’s pretty interesting. Do you want me to?
