When to Move Baby to Their Own Room: UK Guidelines & Practical Tips

One of the most anticipated and slightly nerve-wracking milestones of the first year: moving baby from your room into their own space. Here's what the evidence says about timing, and how to make the transition without derailing everyone's sleep.

What do UK guidelines say?

The Lullaby Trust (the leading UK SIDS charity) and the NHS recommend:

Room-share with your baby (in their own sleep space — cot or Moses basket) for at least the first 6 months.

This recommendation is based on research showing room-sharing reduces SIDS risk — not because parents are "doing something" when the baby is in danger, but because babies who share a room with a sleeping adult tend to have slightly different sleep patterns and arousal thresholds.

The 6-month threshold is evidence-based: after this age, the SIDS risk drops significantly (most SIDS deaths occur before 6 months).

After 6 months: it's your choice

Once baby is past 6 months, the decision of when to move to their own room is entirely yours. There is no medical or safety guidance that says "you must move them at 6 months" — it's simply that the primary reason for room-sharing (SIDS risk reduction) diminishes significantly after this point.

Factors to consider:

• Are you all sleeping better together or apart?
• Does baby wake easily when you come to bed or when you move?
• Is baby ready for more independent sleep?
• Is the nursery room set up and at the right temperature?

Signs baby may be ready for their own room

• Consistently waking when parents come to bed at night
• Able to self-settle (or you're about to sleep train)
• Sleeping in longer stretches already
• Developmentally past the highest-risk period (6 months+)

Making the transition smoother

1. Move during a positive period

Avoid starting the transition during illness, teething, or significant change (travel, nursery starting). Choose a settled week when everyone is well.

2. Keep the sleep routine identical

Baby's bedtime routine — bath, feed, story, song, bed — should be identical in the new room. Familiarity of routine matters more than location.

3. Introduce the new room gradually

Start with naps in the new room before committing to nights. This lets baby acclimatise to the sights, sounds, and smells of the new space while you're awake and available.

4. Use familiar scents

A muslin cloth that smells of mum (or that's been near baby's sleeping space) placed near (not in) the cot can be comforting.

5. Keep a monitor close

The transition from literally hearing every breath to using a monitor can be anxiety-inducing for parents. A video monitor can provide significant reassurance.

6. Expect a few disrupted nights

Most babies take 3–7 nights to adjust to a new sleep space. Short-term disruption doesn't mean it's not working. Stay consistent.

Room temperature in baby's room

Aim for 16–20°C in the nursery. Without you in the room as a heat source, you may need to adjust the sleeping bag tog rating. Use a room thermometer to check.

Safe sleep in the new room checklist

• ✅ Cot meets BS EN 716 or similar safety standard
• ✅ Firm, flat mattress that fits the cot properly
• ✅ No pillows, bumpers, or loose blankets
• ✅ Baby placed on their back, feet to foot of cot
• ✅ Room between 16–20°C
• ✅ Baby monitor working and positioned correctly

What about sleep training?

Moving to their own room is often combined with introducing some form of sleep coaching. This is a personal decision — there are many approaches from the very gentle (pick-up-put-down) to more structured methods. There's no one-size-fits-all, and all age-appropriate approaches are safe when followed correctly.
