My oldest son moved into his own room right around six months old. It felt like the "normal" age at the time, so we did not think twice about it. My youngest, my daughter, was still sleeping in our room as she approached two, and honestly, I was in no rush to change that.
Somewhere between those two kids, my thinking about room sharing shifted completely, and I want to walk you through both the actual guidelines and how we ended up making very different calls for different kids.
This is one of those baby sleep questions where the medical guidance is actually quite clear, but the emotional side of the decision is anything but simple. Every family I know has a different story about when the move happened and how it felt.
Here is what the safety recommendations say, what the research actually means in practice, and how to figure out the right timing for your own family without feeling pressured by anyone else's schedule.
What Do Safe Sleep Guidelines Say About Room Sharing?
The NHS and other safe sleep guidance recommend that babies room share, meaning the baby sleeps in the same room as the parents but on their own separate, firm sleep surface, for at least the first six months.
Room sharing without bed sharing is associated with up to a 50 percent lower risk of sleep-related infant death, largely because it keeps the baby close enough for parents to notice changes in breathing or behaviour while still giving the baby a safe, independent sleep space.
This is different from bed sharing, where a baby sleeps in the same adult bed. A separate sleep surface is the safest option, because pillows, duvets and a soft adult mattress can raise the risk of suffocation and entrapment, but bed sharing can be done more safely when you follow a few basics, which I cover further down.
A bedside crib or bassinet that attaches securely to the parents' bed is a popular way to meet this guidance while still keeping the baby within arm's reach for night-time feeding and settling. It gives you the closeness of having the baby right there without the risks that come with sharing an adult mattress.
We used a bedside crib with all three of our kids for exactly this reason, since it let us stay close without compromising on a separate, safe sleep surface.
Why Our Youngest Stayed in Our Room Longer Than "Average"
The more I have learned about newborn biology, the more I have come to believe that closeness at night is not something babies need to be weaned off quickly, but something that actually matches how they are wired.
In many hunter-gatherer societies that anthropologists have studied, babies and young children sleep close to a parent or family member for years, and the shift toward solo sleeping at a young age is a fairly recent, culturally specific expectation rather than a universal human default.
That does not mean every family needs to do it the same way. It simply means there is no biological deadline forcing a baby into their own room by a certain week or month.
I will be honest about the part that still catches me off guard. My two boys moved into their own room as babies, and I still feel a small pang of something close to loss when I think about how early that separation actually happened.
I am not saying anyone did anything wrong. I am saying the pressure to hit an "own room by X months" milestone is worth questioning, because in a lot of ways, staying close longer is actually the easier and more natural option, not the harder one, even though modern parenting culture often frames it the opposite way.
So let me say it clearly: sharing a room for longer is a really good thing, as long as both your baby and you are happy with it. The same goes for co-sleeping. Done the right way, sharing a bed with your baby is OK, and for many families it simply makes the nights easier.
If you do bed share, keep to the basics every time: a firm, flat mattress, your baby on their back, and no pillows or duvets near your baby. Never fall asleep with your baby on a sofa or in an armchair, and do not bed share if you or your partner have smoked, drunk alcohol or taken medication that makes you drowsy, or if your baby was born premature or with a low birth weight.
Signs Your Baby (and You) Might Be Ready for Their Own Room
There is no single right week for this transition, but a few practical signs tend to matter more than the calendar. Once a baby reliably sleeps through several hours at a stretch, has passed the recommended minimum room-sharing window, and is not waking up frequently enough that a longer walk to another room feels exhausting, many families find the move goes more smoothly.
It also matters how you feel about it. If you are dreading the change or genuinely enjoy having your baby nearby, there is nothing wrong with waiting longer, exactly the way we did with our daughter.
How to Make the Transition Smoother
Moving gradually tends to work better than an abrupt switch for most families. Some parents move the crib to the new room first while still doing all night-time feeds and settling in that room for a week or two, so the baby gets used to the new space with a parent present before being left there alone overnight.
A consistent bedtime routine also becomes even more important once a baby is sleeping farther away, since the same cues that used to work up close need to carry more weight on their own.
Motion made a real difference for us during this transition, though it took having a second baby for me to actually learn that lesson.
With my first son, before I knew about Sleepytroll, I spent what felt like endless hours in the middle of the night standing up and bouncing him by hand, walking back and forth across his room until my arms and legs ached, just to get him settled again after the move to his own room.
Our second son also moved to his own room as a baby, and at first I settled him the same way, by hand. Later, after I had started working at Sleepytroll, I got to test the crib adapters before they were in shops.
From then on, we had a Sleepytroll set up on his crib in sensor mode, so it would start a gentle rocking motion the moment he began to stir, before he fully woke up.
It genuinely helped him settle back down without us having to walk down the hall and stand there bouncing him every single time, which made the whole transition feel far less disruptive for everyone.
Safety Basics for the Nursery
Wherever a baby sleeps, whether that is the parents' room or a separate nursery, the same safe sleep basics apply every single time. Babies should always be placed on their back on a firm, flat mattress with a fitted sheet and nothing else in the sleep space, including no pillows, loose blankets, bumpers, or soft toys.
A comfortable room temperature and a properly fitted sleeping bag, rather than loose bedding, are the safer way to keep a baby warm, and a smoke alarm or carbon monoxide detector nearby is worth checking once a baby has their own separate room.
FAQ: When Can a Baby Sleep in Their Own Room?
What age is a baby's own room considered safe?
Safe sleep guidance, including the NHS, recommends room sharing, not bed sharing, for at least the first six months. After that point, moving to a separate room is considered safe from a guidelines standpoint, though plenty of families choose to wait longer for personal reasons.
Is it bad for a baby to stay in the parents' room longer than a year?
No, there is no medical evidence that staying in the parents' room longer than a year causes harm. Sharing a room for longer is a really good thing as long as both your baby and you are happy with it, whether your baby sleeps on their own safe surface or you bed share following the safe co-sleeping basics. Many families around the world room share well beyond infancy without any negative effects.
How do I know if my baby is ready to move to their own room?
Helpful signs include longer stretches of independent sleep, having passed the recommended minimum room-sharing period, and feeling emotionally ready for the change yourself. There is no single test, so trusting your own read of your baby and your family's needs matters just as much as the general guidance.
Will moving my baby to their own room cause more night waking?
Some babies do wake more for a few nights during any change in sleep environment, including a room move. A consistent routine, a familiar sleeping bag or comfort item, and gentle motion support can all help smooth out that adjustment period.
There is real safety guidance behind room sharing, and it is worth following closely, especially in the first six months. But the exact week you move a baby to their own room after that is genuinely a family decision, not a deadline, and there is no prize for doing it earlier than anyone else.
