Frequently Asked Questions
How can I tell if my baby is overheating at night?
Signs of overheating include damp or sweaty hair and neck, flushed cheeks, rapid breathing, heat rash, and a hot or clammy chest or back when you touch them. Check the back of the neck—if it's warm and damp, reduce layers or swap to a lower-TOG sleep sack. Never rely on hands alone; look for behavior changes like increased fussiness or restlessness as well.
What TOG rating should I choose to prevent overheating?
Use a lightweight TOG for warm rooms and a medium TOG for moderate temperatures. As a rule of thumb: very warm nights benefit from low-TOG or lightweight muslin/cotton; 1.0 TOG is a common middle-ground for temperate conditions. Always pair TOG guidance with room temperature and the baby’s clothing (onesie, pajamas) rather than TOG alone.
Are sleep sacks better than loose blankets for preventing overheating?
Yes—sleep sacks eliminate loose blankets that can bunch up and trap heat. A properly fitted, breathable sleep sack keeps a consistent layer over the baby while allowing airflow and moisture wicking. Choose sleeveless or low-TOG sacks when overheating is a concern, and ensure the neck and arm openings fit according to the manufacturer’s safety guidance.
