Frequently Asked Questions
When should I stop swaddling my baby?
Stop fully swaddling when your baby shows signs of rolling or strong attempts to push up, typically around 2–4 months. Transition gradually: allow one arm out, then both, or switch to a wearable sleep sack to preserve warmth without restricting movement.
How do I prevent overheating when using a sleep sack or swaddle?
Use breathable fabrics (rayon from bamboo or light cotton), choose the correct TOG for room temperature, keep the room between roughly 68–72°F for TOG 1.0–1.5 products, and dress the baby in lightweight layers underneath rather than thicker sleepwear.
Are two-way zippers safer or more convenient?
Two-way zippers are more convenient for diaper changes and reduce how often you disturb a sleeping baby. Look for zipper protectors and well-constructed seams; they also help limit loose fabric and protect delicate skin near the neck and chin.
