Sleep concerns affect nearly every family at some point. When it comes to how long should baby share your room, here is what the guidelines recommend.
The short answer
The AAP recommends room-sharing (baby on a separate surface in your room) for at least 6 months, ideally up to 12 months, as it reduces SIDS risk. If room-sharing significantly disrupts everyone's sleep after 6 months, transitioning to a separate room is a reasonable and safe choice for many families.
Key takeaways
- The AAP recommends room-sharing (baby on a separate surface in your room) for at least 6 months, ideally up to 12 months, as it reduces SIDS risk. If room-sharing significantly disrupts everyone's sleep after 6 months, transitioning to a separate room is a reasonable and safe choice for many families.
- Usually normal when: You transition around 6-12 months
- Call your doctor if: Your baby has breathing concerns requiring close monitoring
- Varies by age — see the age-by-age breakdown below
“To reduce the risk of sleep-related infant deaths, the AAP recommends that infants sleep on their backs, on a firm, flat surface, without any soft bedding.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH guidelines, the AAP recommends room-sharing (baby on a separate surface in your room) for at least 6 months, ideally up to 12 months, as it reduces SIDS risk. If room-sharing significantly disrupts everyone's sleep after 6 months, transitioning to a separate room is a reasonable and safe choice for many families. At 0-6 months, room-sharing is strongly recommended during this period. SIDS risk is highest in the first 6 months. Your baby should sleep on a separate firm surface, not in your bed. A bassinet or mini crib beside your bed is ideal. It is generally considered normal when you transition around 6-12 months. However, you should contact your pediatrician promptly if your baby has breathing concerns requiring close monitoring.
Normal vs. Concerning
By Age
What to expect by age
0-6 months
Room-sharing is strongly recommended during this period. SIDS risk is highest in the first 6 months. Your baby should sleep on a separate firm surface, not in your bed. A bassinet or mini crib beside your bed is ideal.
6-9 months
Many families transition after 6 months. Research shows babies who move to their own room around this time often sleep longer stretches. If room-sharing works for your family, continuing is also fine.
9-12 months
The AAP ideal recommendation extends to 12 months. However, if room-sharing causes fragmented sleep for everyone, the benefits of better sleep quality may outweigh the proximity benefit. Use a video monitor for peace of mind.
12+ months
After 12 months, SIDS risk drops significantly and the room-sharing recommendation no longer applies. Transition when it makes sense for your family.
What to Tell Your Pediatrician
- Describe when you first noticed how long should baby share your room and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if you are severely sleep deprived from room-sharing disruptions.
- Mention if you want to transition but feel anxious about safety.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.

Moving Baby from Co-Sleeping to Their Own Room
The AAP recommends room-sharing (but not bed-sharing) for at least the first 6 months, ideally 12 months. When you are ready to move your baby to their own room, a gradual transition works best. Start with naps in the nursery, then nighttime. Most babies adjust within 1-2 weeks, and many families find that everyone sleeps better with the separation.
Co-Sleeping Safety - Risks and Guidelines
The AAP recommends room-sharing (baby sleeps on their own surface in the same room) but not bed-sharing for the first year. Bed-sharing increases the risk of SIDS and suffocation, especially in the first 4 months, with premature babies, when parents smoke, drink, or take sedating medications, and on soft surfaces. Many families do end up bed-sharing at some point - if you choose to or find yourself doing so, knowing the risk factors and how to reduce them is important for your baby's safety.
Safe Sleep Environment for Baby
The ABCs of safe sleep are: Alone (no bed-sharing), on their Back, and in a Crib (or bassinet) with a firm, flat mattress and no loose items. These guidelines, recommended by the AAP, significantly reduce the risk of SIDS (Sudden Infant Death Syndrome) and other sleep-related deaths. The sleep environment should have no blankets, pillows, bumpers, stuffed animals, or positioners. Room-sharing (baby sleeping in your room but on their own sleep surface) is recommended for the first 6-12 months.

How Long Should Baby Be Awake Between Naps?
The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.
Is a Bath Before Bed Really Necessary?
A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.
How Long Should the Bedtime Routine Be?
An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.
