When to wean
Once your baby becomes frustrated with being swaddled or her sleep deteriorates, it is time to think about weaning her off being wrapped.
Also as your baby starts to roll, she may be unsafe swaddled as tummy sleeping/swaddled babies have a x7 SIDS risk compared to back sleep/swaddled babies.
There is no specific age that you need to stop swaddling, but once your baby is over 4 months it can be good to start the weaning off swaddling process very gradually. Some babies may be ready earlier, while others still enjoying their swaddles for many more months!
If your baby is over 5 months, still swaddled and waking in the night, she may need at least one hand out. This would enable your baby to hold a blankie, suck her fingers or put a dummy back in herself. If you keep both arms in the swaddle past 5 months of age, you are likely to continue to need to help your baby back to sleep!
