When Can Baby Sleep in Their Own Room? (AAP Guidance)

At some point almost every parent lies awake doing the same math: the bassinet is two feet from the bed, nobody is sleeping well, and the empty nursery down the hall is starting to look very appealing. So when is it actually okay to move the baby into their own room?

The honest answer is more flexible than most parents think, and it has changed in the last few years. Here is what the pediatric guidance says, where the real cutoff is, and the one thing people most often get wrong.

The short answer

The American Academy of Pediatrics recommends room-sharing, which means keeping your baby's sleep space in your bedroom but on a separate surface, for at least the first 6 months, and preferably up to a year. Room-sharing this way can cut the risk of sudden infant death by roughly half compared with the baby sleeping in a separate room, and it is far safer than sharing your bed.

That means six months is the earliest point the guidance clearly supports for moving a healthy baby into their own room. Many families room-share longer, and a few find reasons to feel comfortable a bit earlier, but six months is the line worth anchoring to. Until then, the safest setup is a crib, bassinet, or play yard in your room with nothing in it but a fitted sheet.

Why the AAP says "6 months"

Room-sharing is not about you hearing the baby better, though that is a nice side effect. It is a measured safe-sleep intervention. The AAP recommends it specifically because keeping the baby's sleep area in your room "can decrease the risk of SIDSSIDSSudden Infant Death Syndrome: unexplained death of an otherwise healthy infant under 1, usually during sleep. The AAP's ABCs of safe sleep (Alone, on Back, in a Crib) cut the risk by more than half. by as much as 50%."

The recommendation pairs with the rest of safe sleepsafe sleepAAP guideline: baby sleeps Alone (no blankets, pillows, bumpers, or toys), on their Back, in a Crib or bassinet with a firm flat mattress. Room-sharing without bed-sharing is recommended for the first 6-12 months.: baby on their back, on a firm flat surface, in their own space. The point of the room, not the bed, is that your baby gets the protective effect of being near you without the suffocation and entrapment risks that come with an adult mattress, pillows, and blankets.

The duration matters because the first months are when babies are most vulnerable and least able to reposition themselves. Keeping them close during that window, on their own safe surface, is the cautious default.

"At least 6 months" vs. "up to a year": where the confusion comes from

Here is the part that trips people up. You will see two numbers in pediatric guidance, and they are not contradictory.

The current AAP wording is to room-share "for at least 6 months, but preferably up to 1 year of age." In other words, six months is the floor, and a year is the gold standard. An older version of the recommendation leaned harder on the full year, which is why some articles and well-meaning relatives still quote twelve months as if it were a hard rule.

It was never framed as a hard rule. The evidence for the protective effect is strongest in those early months. After six months, the data supporting room-sharing gets thinner, and the AAP itself acknowledges that families weigh practical factors past that point. So if your baby is past six months and everyone sleeps better in separate rooms, you are inside the guidance, not breaking it.

Signs you and your baby may be ready

There is no developmental milestone that "unlocks" the nursery. Readiness is mostly about hitting the six-month floor and your own judgment. Useful signals that the move is reasonable:

• Your baby is at least 6 months old. This is the non-negotiable part.
• They have outgrown the bassinet or can push up, roll, or sit, which means the bassinet is no longer safe regardless of the room.
• Their sleep stretches have lengthened, so you are not crossing the hall every 90 minutes anyway.
• Everyone's sleep is suffering from proximity — every grunt waking you, or your movement waking the baby. Sometimes the room itself is the problem.
• Your monitor and setup are ready so you can still hear and see the baby from the next room.

None of these override the six-month floor. They just help you decide between six months and a year, which is entirely your call.

What most parents get wrong

The most common mistake is treating "their own room" as the risky variable. It isn't. A six-month-old in a proper crib down the hall, on a back, on a firm mattress, with nothing else in the crib, is in a safe sleep setup.

The genuinely dangerous shortcut is the opposite move: pulling the baby into your bed because the back-and-forth is exhausting. Room-sharing means a separate surface in your room, not your mattress. Couches and armchairs are never safe sleep surfaces for a baby, and falling asleep with a baby while feeding on one is one of the highest-risk situations there is. If you are too tired to keep crossing the hall, the answer is to move the crib closer or move the baby's room sooner past six months — not to bring the baby into the bed.

The second mistake is "graduating" the crib by adding comfort items. A bigger room can make a bare crib feel stark, and the temptation to add a pillow, a blanket, or a bumper grows. The rule does not change with the room: until the first birthday, the only thing in the crib is a fitted sheet on the mattress. Soft objects, loose bedding, and bumpers are linked to suffocation, entrapment, and strangulation, full stop.

How to make the move smoother

If you have cleared six months and decided to move, a few practical steps help:

• Keep the rest of the routine identical. Same wind-down, same swaddle-or-sack, same sound machine, same lights-out time. Change one variable, not five. Our guide on building a bedtime routine that actually works walks through a repeatable sequence.
• Reset the safe-sleep basics in the new room. Firm flat crib mattress, fitted sheet only, back sleeping, room not too warm. The full checklist is in our safe sleep environment guide.
• Set up the monitor before the first night, with the camera angled for a full crib view and good night vision, so you are not troubleshooting at 2 a.m. See our baby monitor picks if you still need one.
• Expect a few rough nights. A new room is a new variable, and short-term protest is normal. It usually settles within a week if the routine stays consistent.

If your baby is still in a bassinet and you are not sure whether the next step is a crib in your room or a crib in the nursery, our bassinet-to-crib timing guide covers that handoff.

The bottom line

Room-share on a separate surface for at least the first 6 months, ideally up to a year. Six months is the earliest the guidance clearly supports moving a healthy baby into their own room, and anywhere between six and twelve months is a reasonable, evidence-aligned choice based on how your household actually sleeps. Whatever room they are in, the safe-sleep rules don't change: back, firm flat surface, fitted sheet only, nothing else in the crib, and never the adult bed.
