How can I support my children sleeping together in the same room?
A gentle sleep guide for siblings
I am a great believer in the advantages of siblings sharing a room together.
As a mum of four, it was completely normal in our family for children to share bedrooms. As a sleep consultant, I’ve also supported many families through the transition – from babies moving out of the parents bedroom to siblings learning how to settle and sleep together successfully.
This guide will guide you through:
- The benefits of siblings sharing a room
- Common challenges (and how to manage them)
- When children are ready to share
- Practical bedtime and sleep tips
- A real-life sleep story showing how room sharing can work in practice
Why siblings sharing a room can be a wonderful thing
Many children settle better and feel more secure at night when they’re not alone. The presence of a sibling can be very reassuring, particularly for toddlers and preschoolers who are developmentally prone to night-time fears.
Another lovely benefit of sharing a room is the relationship it nurtures between siblings. Without parental interference, children learn how to:
- Share space
- Respect belongings and boundaries
- Understand privacy
- Build closeness through quiet chats and shared rituals
These skills are valuable preparation for nursery, school and later life – and often develop very naturally when siblings share a room.
For families where room sharing isn’t a choice but a necessity, it can be helpful to remember that there are real advantages. With support and preparation, most children thrive in shared bedrooms.
Are there any downsides to siblings sharing a room?
As with anything, there can be challenges. The most common concern parents have is sleep disruption – particularly if one child is a lighter or less settled sleeper.
It’s true that if one child wakes and cries during the night or early morning, there’s a risk of waking the other. However, children are incredibly adaptable. Over time, most become used to the sounds of a sibling and are able to sleep through them.
This is especially true when parents are responsive. When children learn that you will attend to a wakeful sibling, they don’t feel responsible themselves and are more able to remain asleep.
When is a child ready to share a room with a sibling?
A baby of around six months or older can move directly from your room into sharing with a sibling, provided they are generally settled at night.
Some important safety and emotional considerations:
- Children should not share a bed. Babies and toddlers should always have their own safe sleep space (cot or bed).
- Even when children are older, bed sharing should only happen if both are confident, mobile sleepers and it feels genuinely safe.
- Consider the temperament of your older child. Some children can be physically exuberant or struggle with emotional regulation around younger siblings.
As their parent, you are always the best judge of whether a shared room feels safe and appropriate.
Bedtime routines for siblings sharing a room
If children are close in age
When siblings are fairly close in age, it usually works best for them to:
- Share a bedtime routine
- Go to bed at the same time
After stories and cuddles, aim for them to fall asleep without you in the room, but with the reassurance that you’re close by. Staying until they’re asleep often leads to night waking where children look for your presence again.
Some chatting at bedtime is completely normal and can be a lovely part of bonding. If it starts to go on too long and one child is keeping the other awake, step in calmly and confidently.
If possible, manage this from outside the room rather than going in – your voice alone is often enough.
If one child needs longer to wind down
If an older child needs more time to settle, reading quietly in bed can work well. Using a red light is helpful, as it doesn’t interfere with melatonin (the sleep hormone) production in the same way brighter lights can.
A real-life sleep story: sisters learning to share a room
The children
- Anita, 3½ years old
- Mana, 16 months old
The situation
Mana had recently dropped her night feeds and was sleeping through the night. She was still in a cot in her parents’ room, and the family felt ready for her to move in with her big sister.
Anita was also in a cot but developmentally ready to move into a toddler bed. She was excited about her new bed and about sharing a room with Mana.
At the same time, Mana was transitioning from two naps to one. This meant some days she was overtired by early evening, and on others she was napping too late and struggling to settle at bedtime.
For room sharing to work well, both girls needed to be ready to sleep at the same time.
The sleep plan
1. Manage naps
- Drop Mana’s morning nap or limit it to 20 minutes.
- Her main midday nap needed to end by 3pm to support a 7pm bedtime.
2. Prepare the older sibling
- Two or three days before moving in together, transition Anita into her new bed.
- Give her time to feel confident and comfortable in it.
3. Talk it through
- On the day of the move, explain clearly and positively what’s happening.
- Ask Anita how she feels and really listen.
- Reassure her that if Mana cries, a parent will come and take care of her.
4. Make it special
- Have a light-hearted ‘moving in’ ceremony when Mana’s cot is brought into the room.
- Let the girls role-play bedtime.
- Praise and celebrate generously.
5. Shared bedtime routine
- Bathe the girls together around half an hour before bedtime.
- Read stories together while sitting on floor cushions or the bed.
- Offer milk in cups rather than bottles if appropriate.
- Choose the same final book each night for consistency.
6. Bedtime approach
- Kiss both girls goodnight.
- Place each child into their own bed/cot.
- Tell them you’ll come back to check on them.
- Leave the room without fully closing the door.
Return every few minutes if they are awake and chatting, using calm reassurance and a simple, repeated ‘sleepy phrase’.
If Mana cried, a parent stayed in the room to settle her while reassuring Anita that her sister was tired and safe.
Try to leave the room while both girls are calm but awake. If you need to stay initially, that’s okay – this can be faded over time.
Night wakings and mornings
- Attend to either child promptly if they wake.
- Reassure, reposition and use the same calming phrases as bedtime.
- Avoid ‘musical beds’ – each child stays in their own sleep space.
Before 7am, keep the room calm and dark. Low-level chatting or grumbling can be left, but if distress escalates, stay with them until morning.
At 7am, clearly signal daytime:
- Open curtains
- Turn on lights
- Turn off white noise
Greet both children warmly and praise them – especially the older sibling – for patience and kindness.
The outcome
The first night was exciting and busy, but both girls fell asleep quickly without a parent in the room. Mana woke early the next morning, which woke Anita, and one parent stayed with them until 7am.
Over the following nights, the novelty wore off and both girls began sleeping until close to 7am.
Their parents were delighted to have their bedroom back and felt the change had a positive impact on their own relationship too.
Final thoughts on siblings sharing a room
Sharing a room can be both practical and lovely for siblings. With thoughtful preparation, realistic expectations and responsive parenting, it is often a smoother process than parents anticipate.
Managing the younger child’s naps so that siblings are ready to sleep at the same time is key. For example, if Mana had been six months old rather than sixteen months, she would have needed a longer wake window in the early evening to settle well at 7pm.
As always, every family and every child is different. This guide is intended as supportive guidance rather than a rigid rulebook.
