You know your baby best, after all! Remember that while most people use swaddling as a soothing technique during the newborn stage, and then start to phase it out around 3 or 4 months, it’s not uncommon for babies to be swaddled when they are 6, 7, 8, even 9 months old.

There is no absolute age for when you must stop using a swaddle. How long you swaddle your baby past 3-4 months will have to be determined by you based on your assessment of your babies needs, the risks, the benefits, the mobility of your baby and good old mama intuition. Some babies just absolutely need to be swaddled longer in order to sleep more than 20 minutes at a time.

1 Fold or twist the bottom of the blanket loosely and tuck it under one side of the baby.  Make sure her hips can move and that the blanket is not too tight. “You want to be able to get at least two or three fingers between the baby’s chest and the swaddle,” Dr. Moon explains.
