All You Need to Know About Buying Swaddle Sleep Sacks
Frequently Asked Questions (FAQs)
Once infants begin to roll over independently, they should not wear sleep sacks with swaddle attachments or wraps. Regardless of the chosen sleep solution, the safest position for an infant is always on their back, for naps and nighttime, until they reach 12 months of age.
If an infant is starting to roll over or shows signs of doing so, a sleep sack is a safer choice. However, until the baby can roll over on their own, a swaddle remains a completely safe option.
The swaddle transition should commence when the infant begins to roll over during their sleep, typically between 2 to 4 months of age, to ensure their ability to roll themselves back over if they turn onto their stomach.
A 2019 analysis concluded that infant sleep sacks are as safe, if not safer, than other bedding in preventing sudden infant death syndrome (SIDS).
