(CNN)Swaddling, the art of snugly wrapping an infant in a garment for warmth and security, is a go-to for sleep-deprived parents the world over.
Baby expert upon sleep guru upon wise grandma will recommend it. It’s the first of the storied “5 S’s” in the “Happiest Baby
” method, parenting guru Harvey Karp’s technique for calming newborns and coaxing them to sleep. In some circles, people pay dearly for big squares of muslin or flannel, or special swaddling devices.
In light of all this, parents were understandably alarmed by an analysis of sudden infant death syndrome risk for infants swaddled for sleep, published this week in the journal Pediatrics
“Swaddling babies may increase risk of SIDS,” the headlines blared. Some readers latched on and panicked. But the analysis emphasizes a more nuanced conclusion that supports what many parents and pediatricians already know.
To quote the article: “Current advice to avoid front or side positions for sleep especially applies to infants who are swaddled. Consideration should be given to an age after which swaddling should be discouraged.”
Put another way: Stick to current advice not to place infants to sleep on their stomachs or sides, and stop swaddling as your baby grows — probably around the time he or she shows signs of rolling or begins to break out of this fabric cocoon.
The review of previous research looked at four studies spanning two decades from the United Kingdom, Australia and the United States.
Moon was also involved in that study, which suggested that parents should be aware that newborns are at risk for multiple and simultaneous SIDS risk factors, not just one. This latest study seems to reveal another factor for parents to consider.
The review also underscored another widely held view in parenting circles and pediatrics: Swaddling is helpful but only until a certain point.
“There’s a time to swaddle and a way to swaddle safely and a time to stop,” said Dr. Ari Brown, an Austin, Texas-based pediatrician and author of the Baby 411 book series. “All good things must come to an end.”
Brown says the time to stop is two months in, but others’ advice ranges from three to six months. At that point, the benefits of swaddling diminish as the startle reflex in newborns goes away, and potential risks such as flat head and anencephaly increase, she said.
“Swaddling does have some risks associated with it, and parents need to be aware of safe swaddling techniques and what they can do to reduce the risk and reap the benefits,” Brown said.

The American Academy of Pediatrics has the following recommendations
to help prevent SIDS:
- Babies should always sleep on their backs.
- Always use a firm sleep surface.

- Breastfeed as much and for as long as you can.
- Offer a pacifier at nap time and bedtime.
- Schedule and go to all well-child visits.
- Do not use products that claim to reduce the risk of SIDS, such as wedges, positioners or special mattresses.
- Do not use home cardiorespiratory monitors to help reduce the risk of SIDS.
