When Siblings Should Share a Room

Timing is important when it comes to sibling room sharing. Before you make the change, be sure both your children are sleeping well on their own. A child who still wakes through the night could disrupt the child who has healthy sleep, causing a regression. Parents tend to be hypersensitive to the slightest sounds that might have both children awake and disrupted simultaneously, and responding can cause unhealthy sleep habits.

Make sure the whole family is ready for the transition, too. Are you about to go out of town soon? Is anyone sick, or are things just feeling extra chaotic and stressful lately? If so, it may be best to wait until things stabilize a bit.

How to Successfully Transition Siblings to Sharing a Room

Sharing a room is a big transition. A few simple steps can make the process smoother for everyone. 

Communicate

Talk about the big day well before the big day. Discuss how both siblings will be sleeping in the same room together. Just three days prep is enough to clue your children into the new changes coming their way. If you can, make the transition fun. Have the older child clean up the room, make a welcome sign, and help set up the little one’s bed. Start using words like “ours” and “we” instead of “me” and “mine.” 

Tweak the Routine

On the day you move them, talk about how bedtime might be a little different now, and get them involved. Here is a sample schedule of the bedtime routine for sibling room sharing:

• 6:30: Bath together
• 6:40: Brush teeth, potty, and PJs
• 6:50: Read books together
• 7:00: Kisses to everyone and lights off

Tip: To replace the extra snuggle time you had with each child independently, spend extra time having fun in the bath and reading books.

Be Patient 

Room sharing is going to take some time to get used to, just like any sleep change. Continue to communicate with your children what your sleep expectations are, what the new bedtime routine is, and how great they are doing sharing a room together. 

It can be normal to experience a honeymoon period for a few nights or even a week. Remember, they have never shared a room together in their life!

If the older child starts acting out or rebelling against the new routine, intentionally spend 10-15 extra minutes of one-on-one time with this child. Negative behavior can be a need for attention. Understand that this is an adjustment, give them some extra love and talk with them about how they feel along the way.

Tip: Even if it was a rough night in the beginning, make a big deal when it’s morning! Praise them and let them know how proud you are of them.

Frequently Asked Questions

What if one child falls asleep faster than the other?

That’s very common. As long as both children are calm and staying in bed, different sleep-onset times usually aren’t a problem. Over time, siblings often adjust to each other’s rhythms, especially when the bedtime routine stays consistent.

How long does it usually take for siblings to fully adjust to sharing a room?

Most families see improvement within one to three weeks. Small disruptions early on are normal, but consistency and reassurance usually help things settle as the new routine becomes familiar.

What should I do if my kids keep talking or giggling after lights out?

Some extra chatter is very normal in the early days of room sharing. If both children are calm and staying in bed, it’s usually best to give them a little space to settle on their own. Over time, the novelty wears off and the shared routine helps signal when it’s time to sleep.
