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.
