Safe Sleep — The ABCs
Version 1.0 · Last reviewed July 2026 · Review cadence: Quarterly (immediate on major guideline changes)
EVERY SLEEP, EVERY TIME
A — ALONE. Baby sleeps alone. No bed-sharing, no other people, no pets. Room-sharing without bed-sharing is recommended, ideally for at least the first six months.
B — on the BACK. Always place baby on the back for every sleep, naps included, until the first birthday. Once a baby can roll both ways on her own, she can be left in the position she assumes.
C — in a CLEAR CRIB. A firm, flat sleep surface (crib, bassinet, or play yard with a fitted sheet) and nothing else — no soft bedding, no blankets, no pillows, no bumpers, no toys, no inclined surfaces, no positioners.
