If your baby has not shown signs of rolling yet, you can simply allow them to sleep in the SWADDLE UP™ TRANSITION SUIT until they show signs of trying to roll. Once they show signs of trying to roll over, you must stop swaddling your baby and transition them. Start with one ARMS UP™ wing and one SELF-SOOTHING™ SLEEVE on (cuff folded over). 
After several nights of your baby settling into this routine, remove the ARMS UP™ wing and start bedtime off with both SELF-SOOTHING™ SLEEVES zipped on (cuffs folded over). Once your baby has settled into a routine, you can open the cuffs for true arms-free sleep. 
Some babies transition in a few nights, others can take a few weeks. The SWADDLE UP™ TRANSITION SUIT with SELF-SOOTHING™ SLEEVES is especially helpful for any baby who is having a harder time going from being swaddled to arms-free sleep.
