Start with safety
- A separate sleep space for each child. The NIH Safe to Sleep campaign names a sibling sharing a baby’s sleep surface as a high-risk situation. Every child sleeps in their own bed.
- Keep the crib bare. The CPSC sums it up as “Bare is Best”: a crib, bassinet or play yard should hold only a fitted sheet. Blankets, pillows and stuffed toys stay out for the first year.
- Protect the crib from the toddler. Toddlers love to share. Teach them that the baby’s bed stays empty, and look it over before every sleep.
- Protect the room from the toddler. Put small toys, coins and batteries where a crawling baby can’t get to them, and anchor furniture to the wall.
- Cords. Route monitor and lamp cords well clear of both beds. The CPSC warns that corded cameras should never be placed within three feet of a crib.
- Keep white noise low, if you use it, and put the machine on the far side of the room. A 2014 study found that at maximum volume some infant sleep machines were loud enough to raise hearing concerns.
Putting two children in one room is entirely doable. If they keep waking each other up, it’s the waking that can be fixed — and Actually Sleeping fixes it with both children in mind.
Timing the baby’s move
The AAP recommends that your baby sleep in your room for at least the first 6 months. Beyond that point, when to move is your call. Lots of families find the move easier after night feeds have tapered, since feeding in a shared room tends to wake the toddler. How night feeds are handled depends on your baby’s age and is set in your custom plan.
What really keeps siblings awake
Most children learn to sleep through the everyday sounds a sibling makes. What actually wakes a roommate is generally a pattern: a baby who cries at the end of every sleep cycle because they need help getting back to sleep, a parent who comes in to talk or feed, lights switching on, a toddler who climbs out to investigate. When one child wakes frequently, room sharing gets blamed — but for most families the issue isn’t the room, it’s the night waking.
Mismatched bedtimes and nap times make it harder. Babies generally go down earlier than toddlers and naps seldom line up, so one child often needs the room while the other is using it.
Why a plan makes the difference
Solving sleep for two children sharing a room is as much about logistics as about sleep: which bedtime comes first, where naps take place, and what to do when one child is learning to fall asleep independently while the other is trying to sleep. The right answers hinge on both children’s ages, schedules and habits, and on the layout of your home.

Common questions
How old should a baby be before sharing a room with a sibling?
The AAP recommends that a baby sleep in the parents’ room for at least the first 6 months. From then on, sharing with a sibling is fine, provided each child has a safe sleep space of their own.
Is it OK for my toddler and baby to share a bed?
No. NIH Safe to Sleep identifies a sibling sharing a baby’s sleep surface as a high-risk situation. Your baby needs a crib, bassinet or play yard of their own, with only a fitted sheet.
What should I do if the baby keeps waking the toddler?
Siblings frequently learn to sleep through everyday noise. If one child is repeatedly waking the other, the root cause is usually the baby’s own night waking rather than the room. That waking is exactly what an Actually Sleeping plan resolves, with the shared room factored in.
