When Can My Baby Sleep in Their Own Room? UK Guidance
The cot is built. The room has been ready for months. And somewhere around the six-month mark, the question starts arriving from all directions: is the baby in their own room yet?
Behind it, usually, are two competing pressures.
On one side, there is the promise that everyone sleeps better apart, plus a cultural clock that treats the move as a milestone you are falling behind on. On the other, there is your own instinct, which may be nowhere near ready to put a corridor between you and a small person you currently check is breathing on a semi-hourly basis.
So let's take the question properly: what does the safety guidance actually say, will moving your baby help everyone sleep better, how can you tell when the time feels right, and how can you make the move gently when it does? Spoiler for anyone feeling pressured: six months is the minimum recommended period for room-sharing, not an eviction date.
The Short Answer: What UK Guidance Says
The safety part first, because it is the one clear line in this whole topic.
The Lullaby Trust and the NHS recommend that your baby sleeps in the same room as you, in their own separate sleep space, for every sleep during at least the first six months. That includes daytime naps as well as nighttime sleep. Room-sharing during these first six months is associated with a lower risk of sudden infant death syndrome (SIDS), which means a baby under six months should nap where you are, in a cot or Moses basket in the room with you, rather than alone upstairs. A monitor can be useful, but it does not replace having your baby in the same room during this period.
After six months, there is no deadline. The guidance does not require a six-month-old, a nine-month-old or a sixteen-month-old to be in their own room. You can make the move when your current arrangement stops working for your family and you feel ready for the change, while continuing to follow the rest of the safer-sleep guidance wherever your baby sleeps.
One more option deserves naming because it is often treated as unmentionable: continuing to share a room is a legitimate choice, not a failure to progress. If everyone is sleeping and nobody wants to move anybody, there is no clock running. Room-sharing and bed-sharing are not the same thing, but many parents bed-share at some point, whether planned or unplanned, which is why knowing how to reduce the risks matters.
The Lullaby Trust publishes clear guidance on making co-sleeping safer, and if that is the road you are on rather than a room move, this piece on co-sleeping more safely walks through it properly.
Will Everyone Actually Sleep Better Apart?
Here is the honest picture behind the promise.
Some families do sleep better separately. Some babies are noisy sleepers whose every snuffle wakes a light-sleeping parent, some parents are noisy sleepers who return the favour, and for some pairs, a wall between them means everyone can stir without waking everyone else. If that is the dynamic in your room, moving your baby after six months can make a real difference, and you should not feel a flicker of guilt about wanting it.
But the promise is often oversold. Your baby may still wake because moving rooms changes their proximity to you, not their biology. Night waking remains normal well beyond six months, so the move can trade snuffle-disturbance for corridor commutes. Which of those costs you more sleep depends entirely on what is happening in your house. If your baby needs you frequently during the night, having them two feet away may be considerably easier than getting up and going into another room several times.
The timing can matter too. Separation anxiety often becomes more noticeable during the second half of the first year, which does not mean you cannot move your baby during that period, but it may mean they need more reassurance while the new room becomes familiar. As with most things involving babies, there is no universal best age hiding somewhere between six and twelve months. There is only the point at which the change makes sense for your particular baby and family.
How to Tell When You're Both Ready
There is no official readiness checklist your baby has to pass after six months, but it can help to look at what else is happening. A relatively settled period, with no illness, obvious discomfort or major family change already under way, may make the move feel more manageable. If your baby is starting nursery, you are moving house or they are going through a particularly unsettled developmental patch, you may decide that one substantial change is enough for now.
Temperament matters as well. A fairly adaptable baby may take the new room in their stride, while a sensitive or slow-to-warm-up baby may need much longer to become comfortable with different sights, sounds and distance from you. If that sounds like your baby, everything below still applies. You may simply need to move more slowly and offer more of your presence while they adjust.
Crucially, you need to feel ready too. Parental readiness is not a fluffy extra. A parent lying awake staring at the monitor may sleep far worse than a parent listening to their baby breathe beside them, and the whole point of this was supposed to be more sleep. There is no prize for moving your baby early and no penalty for waiting until the decision feels comfortable rather than pressured.
How to Move Your Baby to Their Own Room
The theme throughout is simple: change as little as possible at once and let familiarity do most of the work.
Make the new room familiar before your baby sleeps in it
Spend relaxed daytime there for a while first, perhaps for feeds, play, nappy changes or the bedtime story, even if sleep still happens in your room. You want it to feel like part of your baby's known world before you ask them to sleep there. If your baby is still under six months, they should continue sleeping in the same room as you, but you can begin building positive associations with their future bedroom while they are awake.
Move the bed, not the whole routine
Keep the rest of sleep as familiar as possible: the same cot if that is practical, the same sleeping bag, the same wind-down, the same white or pink noise if you use it, and the same way of settling. The room is already one significant change. Feeding, rocking, cuddling or staying close does not need to disappear at the same time.
Begin with whichever sleep is normally easiest
For some babies, that will be the first nap of the day. For others, daytime sleep is far more difficult and bedtime is the most reliable place to begin. There is no rule saying you have to start with a nap, so choose the sleep that usually involves the least struggle and see how your baby responds.
Stay for as long as your baby needs you to
Settle your baby in the new room exactly as you would have done in yours: fed, held, rocked or with you sitting beside the cot. There is no schedule dictating that you should offer less support each night. Some babies will barely react to the move, while others will need you close for longer, and neither response means anything has gone wrong. You can ease back when it feels natural rather than because a plan says it is time.
Don't make it all or nothing
A rough night or two does not necessarily mean the move was a mistake, but nor do you have to push on regardless. Respond to your baby as you normally would, and if you end up back in your old room together for part of the night, that is simply where you both needed to be. You can try the new room again the following night, pause for a week or use it for only part of the night while everyone adjusts. Changing your approach in response to your baby isn't indecision. It's responsiveness.
Check the room itself
Aim for a temperature between 16°C and 20°C, make sure the room is dark enough for sleep, particularly during early summer mornings, and use a clear, firm and flat sleep space in line with the Lullaby Trust guidance. Keep the cot away from blind cords and no pillows, duvets, bumpers, sleep positioners and soft toys. You may choose to use a monitor so you can hear or see when your baby needs you, but remember that a monitor does not prevent SIDS or replace the usual safer-sleep guidance.
If the Move Keeps Failing
If the move is making sleep considerably harder, it is worth looking at what might be getting in the way rather than assuming your baby simply needs to get used to it. The timing may be difficult because they are ill, uncomfortable, particularly sensitive to separation or already adjusting to another change. They may need longer to become familiar with the room, more of your presence while settling or a slower transition between the two spaces.
It is also worth checking your expectations. Moving rooms can help if you and your baby are repeatedly disturbing one another, but it cannot remove every reason a baby wakes. If they were waking for reassurance, hunger or discomfort before the move, they may continue to do so afterwards, except now you have a corridor to cross as well.
And sometimes the arrangement itself simply is not working for your family yet. If the only thing pushing the move is the calendar rather than anybody's actual unhappiness, it is allowed to wait. The room will still be there in a few weeks or months, and trying again later is not going backwards. It is noticing what your family needs and responding accordingly.
Whatever anybody at the baby group says, there is no version of this where your baby goes to university still sleeping in a cot beside you. They will move eventually. You do not need to rush the process to prove that they can.

Frequently Asked Questions
Can my baby sleep in their own room at four months?
UK safer-sleep guidance recommends that babies sleep in the same room as a parent, in their own separate sleep space, for every sleep during at least the first six months. That includes daytime naps. However ready the nursery may be, a monitor does not replace room-sharing during this period.
Do babies sleep better in their own room?
Some do and some do not. Sleeping separately may help if you and your baby repeatedly disturb one another, but moving rooms does not prevent normal night waking. What changes is whether you hear every snuffle and how far you have to travel when your baby needs you, so judge it by what is happening during your own nights rather than what somebody else promises will happen.
Is six months a deadline for moving my baby into their own room?
No. Six months is the minimum period for which UK guidance recommends room-sharing, not a date by which your baby must leave your room. You can continue sharing for as long as the arrangement is safe and works for your family.
Should I start with a nap or bedtime?
Start with whichever sleep is normally easiest for your baby. Some babies settle well for their first nap, while others find daytime sleep much harder and are far more receptive at bedtime. Keep the usual routine and way of settling, and let your baby's response guide what you try next.
How do I get my baby used to sleeping in their own room?
Spend relaxed time in the new room together first so it feels familiar rather than strange. You can play, feed, change nappies or read stories there before introducing sleep. When you do begin, keep the usual sleeping bag, wind-down, sounds and way of settling, and stay with your baby for as long as they need you.
My baby won't settle in their own room. Should I give up?
You do not have to think of it as giving up. You can slow the transition down, offer more reassurance or return to sharing a room for now and try again later. It is also worth checking whether illness, discomfort, separation anxiety, the room temperature, early-morning light or sleep timing could be contributing. It may simply not be the right fortnight.
When should I move my baby if we've been co-sleeping?
There is no fixed deadline. If you want to make the transition gradually, you could begin with your baby sleeping in a suitable cot beside your bed, so moving onto their own sleep surface and moving into another room become two separate changes. Continue settling and responding to them as you normally would while each step becomes familiar.
