Six months is one of the most natural times to move your baby out of your bed and into their own sleep space. At this age, most babies are developing regular sleep cycles for the first time, and many have the biological foundation to sleep longer stretches without feeding. That doesn’t mean the transition will be effortless, but it does mean your baby is developmentally ready for it.
Why Six Months Is a Good Time
Babies generally don’t develop regular sleep cycles until around 6 months old. Before that point, their sleep architecture is more disorganized, which makes independent sleep harder. By six months, the brain has matured enough to consolidate sleep into longer blocks, giving you a real window to establish new habits.
Timing matters for another reason: separation anxiety. While some babies show signs of it as early as 4 to 5 months, most don’t develop strong separation anxiety until around 9 months, when they fully grasp that you still exist even when you’re out of sight. If you start the transition now, you’re working in a sweet spot before that anxiety peaks and makes nighttime separations significantly harder.
Set Up the Right Sleep Environment
Before you change any routines, make sure the crib and room are set up for success. Keep the room temperature between 68 and 72 degrees Fahrenheit. Anything above 72 degrees may be too warm. If the room runs hot, a fan can help with air circulation and has been associated with a lower risk of SIDS when temperatures climb above 70 degrees. Dress your baby in clothing appropriate for the room temperature rather than piling on blankets.
Keep the room dark during sleep times. Blackout curtains help, especially in summer. A white noise machine can replicate the constant ambient sound your baby is used to when sleeping near you. If your baby has been sleeping against your body, placing a recently worn (unwashed) shirt near the crib, but not inside it, can offer a familiar scent. The crib itself should have a firm mattress with a fitted sheet and nothing else: no pillows, blankets, bumpers, or stuffed animals.
Start With the Crib in Your Room
Going from your bed straight to a separate nursery is a big leap. A gentler first step is placing the crib right next to your bed. This lets your baby get used to sleeping on a separate surface while still being close enough to hear you breathe, smell you, and be soothed quickly when they wake. Many families spend one to two weeks on this step before moving the crib to another room.
During this phase, put your baby in the crib drowsy but awake whenever possible. This is the single most important habit shift in the entire transition. Babies who fall asleep in your arms or at the breast and then get transferred to a crib often wake up disoriented and upset, because the environment changed while they were unconscious. Falling asleep in the crib teaches them that the crib is where sleep happens.
Move to the Nursery Gradually
Once your baby is consistently falling asleep in the crib beside your bed, it’s time to move the crib into their own room. Expect some protest. This is normal and not a sign that the transition is failing.
The “camping out” method works well for this stage. Set up a mattress or sleeping bag on the floor of your baby’s room so you can respond quickly to wake-ups without bringing them back to your bed. You’re not creating a new co-sleeping arrangement. You’re giving yourself a temporary base to help your baby adjust. Most families can phase themselves out of the baby’s room within about five nights.
Each night, try to increase the physical distance between you and the crib. Start right beside it. After a couple of nights, move to the middle of the room. Then near the door. Then outside the door with it cracked open. Your baby gradually learns that they can fall asleep and stay asleep without you right there.
Handling Night Wakings
Your baby will wake up at night during this process. Not all babies know how to put themselves back to sleep, and that’s a skill they’re learning, not something they’re born with. When your baby wakes, wait a moment before responding. Sometimes they’ll fuss briefly and drift back off. If the crying escalates, go in and offer comfort: a pat on the chest, a quiet “shh,” your hand on their belly. Keep these check-ins short, around one to two minutes, and try not to pick them up every time.
If you’re using timed check-ins (sometimes called graduated extinction), the idea is to slowly increase how long you wait before going in. You might start at three minutes, then five, then eight. On each following night, the intervals stretch a bit longer. The goal isn’t to ignore your baby. It’s to give them progressively more space to figure out self-soothing on their own while reassuring them that you’re still nearby.
Around 6 months, some babies start waking more at night even if they’d been sleeping through. This is often driven by early separation anxiety rather than hunger, and it’s a normal developmental phase. Knowing this can help you stay the course rather than assuming the transition itself is the problem.
If You’re Breastfeeding
Breastfeeding and co-sleeping tend to reinforce each other. Having your baby right next to you makes night feeds effortless, and many breastfeeding parents find that co-sleeping extends their nursing relationship. So moving your baby out of your bed can feel like it threatens your milk supply or your feeding routine.
In practice, your supply will adjust as long as you keep feeding on demand during the day and respond to genuine hunger cues at night. At 6 months, many babies are starting solids, which gradually reduces the caloric pressure on nighttime feeds. You don’t need to stop night feeding altogether to end co-sleeping. The key distinction is feeding your baby in a chair or rocker, then placing them back in the crib drowsy, rather than nursing them to sleep in your bed.
Some parents find it helps to have a partner handle one or two of the night wake-ups during the first week. If your baby smells breast milk, they’re more likely to expect a feed. A different caregiver offering a pat and some quiet reassurance can help break the nurse-to-sleep association faster.
What a Realistic Timeline Looks Like
Most families see meaningful progress within one to two weeks, but the full adjustment can take three to four weeks before sleep feels truly settled. The first three nights are typically the hardest. Crying often decreases noticeably by night four or five. If things feel like they’re getting worse after a full week with no improvement at all, it’s worth reassessing whether your baby is teething, getting sick, or hitting a developmental leap that’s temporarily disrupting sleep.
Setbacks are normal. A night of travel, an illness, or a growth spurt can send you back a few steps. That doesn’t erase your progress. Once your baby has learned that the crib is a safe, familiar place to sleep, they’ll return to that baseline faster than you expect. Consistency over the following nights matters more than any single rough night.
Practical Tips That Make a Difference
- Build a bedtime routine: A predictable 15 to 20 minute sequence (bath, pajamas, book, song, crib) signals to your baby that sleep is coming. Do the same steps in the same order every night.
- Time it right: Watch for sleepy cues like eye rubbing, yawning, and fussiness. Starting the transition when your baby is hungry, overtired, or not feeling well makes everything harder.
- Use naps as practice: Putting your baby in the crib for daytime naps helps them build a positive association with the space outside of the higher-stakes nighttime hours.
- Stay boring at night: Keep the lights dim, your voice low, and interactions minimal during night wakings. You want your baby to understand that nighttime is not playtime.
- Pick one approach and stick with it: Switching strategies every other night confuses your baby and resets the learning process. Commit to a method for at least five to seven nights before deciding it isn’t working.
