How long should my baby room share with us?

The AAP’s guidance

The American Academy of Pediatrics advises parents to sleep in the same room as their baby — though not the same bed — for at least the first 6 months. Your baby sleeps on their back in a crib, bassinet or play yard of their own, near your bed. On its parent site, the AAP notes that room sharing can cut the risk of SIDS by as much as 50% and is safer than bed sharing.

Six months is a floor, not a deadline. The guidance doesn’t require you to move your baby out at 6 months, nor does it require you to keep them in your room beyond that.

Sleep after the 6-month mark

A 2017 study published in Pediatrics tracked first-time mothers and their babies. By 9 months, babies who had moved to their own room before 4 months were sleeping 40 minutes more each night than babies who were still room sharing, and their longest stretch ran 100 minutes longer. Families who room shared were also roughly four times as likely to switch to overnight bed sharing at 4 and 9 months.

Because the study was observational, it points to an association rather than proving the room caused the difference — and it doesn’t alter the AAP’s advice to room share for at least the first 6 months. Even so, the pattern lines up with what plenty of parents experience: you hear every grunt, you react to sounds your baby would have slept through, and your baby hears you when you come to bed.

Room sharing is a safety recommendation, and it can sit perfectly well alongside good sleep. When it doesn’t, the part you can fix is usually how your baby falls asleep — which is what Actually Sleeping works on, whichever room your baby sleeps in.

Signs room sharing is costing you sleep

• Your baby is older than 6 months and the two of you wake each other several times a night.
• You respond to every noise, and your baby has come to expect it.
• Your baby stirs when you get into bed or roll over.
• You catch yourself bringing your baby into your bed in the small hours.

The room is seldom the whole story

Moving your baby to their own room helps if you are the source of the waking — your noise, your movement, how quickly you respond. It won’t help a baby who wakes because they need feeding, rocking or holding to get back to sleep between sleep cycles. Those babies tend to wake just as often in a new room, and parents simply end up walking further at 2 a.m. Most families who come to Actually Sleeping have already tried solutions on their own, often including a room change.

What can be fixed is how your baby falls asleep. Dr. Sam writes a plan for your baby that works with your real setup — whether your baby sleeps in your room, in their own room or in a shared one. You get bootcamp-style coaching before the first night and daily 1:1 check-ins afterward. Read sleep training while room sharing, and hear from families in our 129 client video reviews.

When your baby changes rooms

Every safe-sleep rule carries over to the new room until your baby’s first birthday: back to sleep, in a crib with a firm, flat mattress and just a fitted sheet, and no pillows, blankets, bumpers or soft toys. Keep cords from monitors and lamps well clear of the crib.
