You can stop swaddling your baby when the baby starts to roll over which is between the ages of 2 months to 4 months old.
By 2 to 4 months of age your baby may be able to roll over onto their tummy but not yet be able to roll back over themselves.
Once the baby starts to try to roll over they should stop being swaddled.
While your baby may not actually start to roll over until they are 3 months to 4 months old, it is safest to stop swaddling your baby before your baby rolls over.
When you do stop swaddling your baby, you should stop swaddling your baby gradually.
Start by leaving one of the baby's arm or both arms out of the swaddle while you keep the rest of the baby's body wrapped.
Over time you can gradually increase the amount of freedom your baby has out of the swaddle until the baby is comfortable sleeping without being swaddled.
An alternative to swaddling is a sleep blanket or wearable blanket which are bodysuits with blanket like material.
The wearable blankets or sleep sacks are perfect for baby's that want to feel comfortable an warm but need a little more wiggle room than a regular swaddle provides them.
