Frequently Asked Questions
Is muslin safe for newborns in hot weather?
Yes—when chosen for breathability and used correctly. Single-layer or lightweight cotton muslin allows airflow and helps reduce overheating. Avoid heavy blankets, check baby’s neck and chest for warmth rather than hands or feet, and follow safe sleep guidelines (place baby on their back in a bare crib).
Should I use a swaddle or a wearable sleep sack in summer?
Both can work. Traditional swaddles in single-layer muslin are great for daytime naps and flexible use, while a sleeveless wearable sleep sack with a low TOG rating is better for overnight sleep when you want to eliminate loose blankets. Choose based on your infant’s sleep routine and the room temperature.
How do I care for muslin swaddles to keep them breathable and soft?
Machine wash on a gentle cycle with mild detergent and tumble dry low or line dry. Pre-washed muslin often softens with use; avoid high-heat drying and harsh detergents that can weaken fibers over time. Inspect seams and zippers on wearable sacks regularly for signs of wear.
