How to Choose the Right Swaddle

A few practical points to help you pick a swaddle that fits your baby and your routine.

  1. Fit and size: Look for a swaddle that holds arms snugly without constricting hips. One-size designs can fit many babies, but check product notes for weight or size guidance.
  2. Material and breathability: Choose natural, breathable fabrics like cotton for newborn skin and to reduce overheating. Machine washable materials save time after leaks and spit up.
  3. Ease of use: Consider how you will swaddle during nighttime changes, feedings, and travel. Fast, repeatable closures help tired parents keep baby calm.
  4. Safety first: Stop swaddling as soon as your baby shows signs of rolling. Always place baby on their back in a clear sleep space.
  5. When to stop: Most babies begin to roll between two and six months. Transition away from swaddling once rolling starts to reduce risk.
