Newborn Sleep
Safe sleep, realistic expectations, wake windows, and how to survive the night feeds of the first 12 weeks.
What's Normal for Newborn Sleep
Safe Sleep: The ABCs
Alone
Baby sleeps alone in their own sleep space - No bed-sharing, no siblings, no pets in the cot
Back
Always place baby on their back - Every sleep, every time, until 12 months of age
Crib
Firm, flat, safe surface - Cot, crib, or bassinet. No soft objects inside.
Safe sleep dos
- ✓Room-share (not bed-share) for at least 6 months
- ✓Room temperature 24–26°C - Dress lightly in Singapore's heat
- ✓Use a firm mattress that fits snugly in the cot
- ✓Light muslin swaddle only - Arms out once baby can roll
- ✓Pacifier at sleep time reduces SIDS risk (after BF established)
- ✓Keep the room dark for night sleeps to help circadian rhythm develop
Sleep hazards to remove
- ✗Pillows, quilts, duvets, soft toys inside the cot
- ✗Cot bumpers (suffocation risk even if marketed as 'breathable')
- ✗Sleeping in bouncer, swing, or car seat outside the car
- ✗Positioner wedges or anti-reflux supports in cot
- ✗Weighted blankets or weighted swaddles
- ✗Sleeping on a sofa or armchair - Especially while feeding
Sleeping in Singapore's Heat
Overheating is a known risk factor for SIDS. Singapore's climate requires parents to think carefully about sleep clothing and room temperature.
Ideal environment
- ✓Air-conditioning set to 24–26°C
- ✓Ceiling or standing fan is fine - Don't point directly at baby
- ✓Single cotton bodysuit or onesie is usually sufficient
- ✓Light muslin swaddle if baby prefers being wrapped
- ✓No hat indoors - Babies regulate temperature through their head
Signs of overheating
- !Sweating on the back of the neck
- !Damp hair on the back of the head
- !Flushed, red face
- !Rapid or laboured breathing
- !Restless or frequent waking
If baby feels hot to the touch on chest or back, remove a layer. Check for fever (≥38°C) and see a doctor.
Wake Windows & Sleepy Cues
A "wake window" is the maximum time a baby can stay happily awake before needing to sleep again. Keeping a newborn awake too long leads to overtiredness - Which paradoxically makes it harder to sleep.
| Age | Wake window | Naps/day | Total sleep |
|---|---|---|---|
| 0–4 weeks | 45–60 min | 4–6 | 16–18h |
| 4–8 weeks | 60–90 min | 4–5 | 15–17h |
| 8–12 weeks | 75–90 min | 3–4 | 14–16h |
| 3 months | 90 min–2 hr | 3–4 | 14–15h |
Sleepy Cues - Act Before Overtired
Early cues (start settling now)
- ✓Staring blankly or zoning out
- ✓Slowing movements
- ✓Yawning once
- ✓Quieting down
Late cues (already overtired)
- !Eye-rubbing
- !Ear-pulling
- !Fussing or crying
- !Arching back, hard to settle
Settling Techniques for Newborns
Sleep training is not appropriate for newborns under 4 months. Instead, focus on responsive settling and gradually introducing good habits.
Swaddle
Arms snug, hips loose - Mimics the womb. Use a thin muslin in Singapore. Arms-out once baby shows rolling signs.
Shush-pat
Rhythmic shushing (louder than you'd expect) combined with gentle patting on the back. Matches the sound level baby experienced in the womb.
White noise
50–65dB white noise (rain, fan, or white noise machine) extends sleep stretches. Keep at cot distance, not directly in ear.
Dummy/pacifier
Offers comfort and sucking satisfaction. Safe from 3–4 weeks if breastfeeding is established. Reduces SIDS risk at sleep times.
Contact naps
Completely normal and healthy in the newborn phase. Helps baby regulate heart rate and temperature. Not a bad habit at this age.
Drowsy but awake
Begin placing baby down when drowsy but not fully asleep after 6–8 weeks - The foundation of independent sleep later without formal sleep training.
