Swaddles & Sleep Sacks

A snug baby swaddle recreates the secure, womb-like feeling newborns crave and helps calm the startle reflex that wakes them. As your baby grows and starts to roll, a baby sleep sack (also called a wearable blanket) becomes the safer choice — it keeps your baby warm all night without loose bedding in the crib.

Choosing the Right Sleep Layer

Look for soft, breathable fabrics like cotton and muslin, a TOG rating suited to your room temperature, and an easy two-way zipper for quick night changes. A lightweight muslin blanket is perfect for warmer rooms, stroller naps and tummy time, while a cozier wearable blanket suits cooler nights.

Safe Sleep, Made Simple

Every PUFFLY sleep product is chosen with safe-sleep guidance in mind: firm, flat surfaces, no loose blankets or pillows in the crib, and breathable layers. We’re a twin-mom founded brand — we know how much a good night matters.

Baby Sleep — FAQ
What is the difference between a swaddle and a sleep sack?

A swaddle wraps a newborn’s arms snugly to calm the startle reflex. A sleep sack (wearable blanket) leaves the arms free and is used once a baby can roll — it keeps them warm without loose bedding.
When should I stop swaddling my baby?

Stop swaddling as soon as your baby shows signs of rolling over, usually around 8–12 weeks, and switch to a sleep sack.
Are sleep sacks safe for newborns?

Yes. Sleep sacks are widely recommended as a safe alternative to loose blankets. Choose the correct size and a TOG rating suited to the room temperature.
What fabric is best for baby sleep products?

Soft, breathable natural fabrics like cotton and muslin help regulate temperature and reduce the risk of overheating.
