Ask five people for sleep advice and you'll get five different answers — half of them outdated, some of them flatly unsafe. Here's a plain-language look at some of the most common myths, and what's actually recommended.
This is general information, not medical advice — always talk to your pediatrician about what's right for your baby.
Myth: A light blanket in the crib is fine, as long as it's small.
Fact: Loose blankets, pillows, and crib bumpers are all advised against for infant sleep, regardless of size or weight. A wearable blanket or sleep sack is the recommended alternative — it keeps baby warm without any loose fabric near the face.
Myth: Once a baby can roll over, sleep position doesn't matter anymore.
Fact: The general guidance is to place baby on their back for every sleep until their first birthday. Once a baby can reliably roll both ways on their own, it's generally fine to let them settle into whatever position they land in — but you still start every sleep on their back. This is a good one to talk through with your pediatrician as your baby hits this milestone.
Myth: Swaddling prevents SIDS.
Fact: Swaddling can help soothe the startle reflex and support better sleep, but it isn't a SIDS-prevention tool on its own. Safe swaddling means baby's hips can move freely, arms are positioned so they can't work loose over the face, and swaddling stops once a baby shows signs of starting to roll.
Myth: Room-sharing and bed-sharing are basically the same thing.
Fact: They're treated very differently in sleep safety guidance. Room-sharing — baby in their own sleep space in your room — is commonly recommended for at least the first six months. Bed-sharing, where baby sleeps in the same adult bed, carries different risk considerations and is a conversation worth having directly with your pediatrician based on your specific situation.
Myth: A fussy, wakeful baby means something's wrong with how they sleep.
Fact: Newborn sleep is genuinely fragmented and unpredictable — that's typical, not a sign you're doing something wrong. Consistency in the sleep environment (a dedicated sleep sack, a consistent room temperature, a simple routine) helps more than any single trick, and it gets easier as babies grow.
The through-line in all of this: simple, consistent basics beat whatever the newest trend is. A well-designed sleep sack, a clear crib, and a back-to-sleep habit will do more for your peace of mind than most of what you'll read online — including this post. When in doubt, your pediatrician is always the better source than the internet.
