Safe sleep basics, in plain language

Safe sleep guidance can feel like a long list of rules — here's the short version of what actually matters most, based on widely recommended pediatric guidance.

The core rule: back, alone, crib

• Back to sleep — every sleep, every time, until baby can reliably roll both ways on their own.
• Alone in their own sleep space — a crib or bassinet, not a parent's bed, couch, or armchair.
• A firm, flat surface — no soft mattresses, no inclined sleepers.

Keep the sleep space bare

• No loose blankets, pillows, bumpers, or stuffed animals in the crib for the first year — they're a suffocation risk, even though a cozy-looking crib is tempting to set up.
• A fitted sheet only on the mattress.
• If it's cold, a wearable blanket (sleep sack) is the safer alternative to loose bedding.

Room-sharing, not bed-sharing

Most guidance recommends baby sleep in the same room as a parent, in their own sleep space, for at least the first 6 months — this is associated with lower risk, without the added risks of sharing an adult bed.

Other things that help

• Avoid overheating — dress baby for the room temperature, not extra layers "just in case."
• Offer a pacifier at sleep times once breastfeeding is well established, if you use one — it's associated with lower risk.
• Keep smoke exposure away from baby's environment entirely.

None of this has to be perfect

Life with a newborn is messy, and there will be nights that don't go by the book. The goal is to make the default, everyday setup as safe as possible — not to panic over one exhausted middle-of-the-night lapse.
