Frequently Asked Questions
Can swaddling cause a newborn to overheat in summer?
Yes—overly thick fabrics, tight multi-layer wraps, or heavy accessories can trap heat. To avoid overheating choose lightweight muslin or bamboo-viscose blends, use minimal layers, and check the baby regularly for signs of overheating (damp hair/skin, flushed cheeks).
Which material is best at keeping babies cool: cotton, bamboo viscose, or synthetic wicking fabric?
Bamboo-derived viscose and open-weave cotton muslin are both excellent for breathability and moisture absorption; synthetic moisture-wicking fabrics can be very effective at pulling sweat away but may feel different against skin. Choose based on whether you prefer a natural feel (bamboo/cotton) or engineered moisture control (premium synthetic blends).
How can I tell if my baby is too hot while swaddled?
Check the baby’s neck and back of the head—if they feel sweaty or very warm, reduce layers. Other signs include flushed or red skin, rapid breathing, or restlessness. Hands and feet may be cool; focus on the torso temperature for overheating signs.
