As soon as your baby starts showing signs of trying to roll, you must transition to “arms-free” sleep. Making the move from the secure feeling of being swaddled to sleeping with arms free can be upsetting for some babies… & their parents

The Swaddle UP TRANSITION BAG enables you to zip off one wing at a time, allowing your baby to slowly adjust to “arms-free” sleep. A genius solution that will help you preserve your peaceful sleep routine.

Three easy steps:

Keep both wings attached until your baby is ready to transition
Once your baby starts to show signs of independent rolling, wait till baby is asleep and then zip off one wing so that one arms is free and one arm is still swaddled. This will allow your baby to get used to the sensation of having one arm out.
After a few nights, simply remove the other wing
