Every year in the U.S., about 3,500 babies die suddenly and unexpectedly during sleep — and most of these deaths are preventable. The rule I give every family, every nap: Alone, on the Back, in a Crib.
What the ABCs actually mean
A
Alone
Alone means your baby sleeps on their own, separate, bare surface — no pillows, no blankets, no stuffed animals, no loose bedding of any kind.
B
Back
Back means every single sleep, for the entire first year — naps included, not just nighttime.
C
Crib
Crib means a firm, flat surface designed for infant sleep, with nothing else in it.
Where families get tripped up
Traveling or staying somewhere new is exactly when families are tempted to bend these rules — which is exactly when they matter most. A hotel room, a relative’s house, a long car ride: the setting changes, but the ABCs don’t.
Hotel and travel cribs
Check that any crib provided meets current safety standards — firm mattress, tight-fitting sheet, no drop-side rails. When in doubt, bring a travel crib you know is compliant rather than relying on what’s provided.
Car seat naps
Car seats are designed for travel, not routine sleep. If your baby falls asleep in the car, that’s fine for the ride — but move them to a flat, safe sleep surface once you’re at your destination rather than letting a car seat nap continue for hours.
Bed-sharing
Room-sharing (baby’s crib in your room) is recommended and reduces risk. Bed-sharing (baby sleeping in the adult bed) significantly increases risk, especially in the first months, on soft surfaces, or when caregivers are especially tired.
The bottom line
Safe sleep isn’t complicated, but it does require sticking to the same rule every time — including the times it’s inconvenient. Alone, on the Back, in a Crib, everywhere your baby sleeps.
If you have questions about your specific setup — a small apartment, frequent travel, multiple caregivers with different habits — I’m glad to talk it through.
