Safe Sleep: The ABCs
Alone
Baby sleeps alone - No bed-sharing, no siblings or pets in the sleep space
Back
Always place baby on their back - Every sleep, every time, until 12 months
Crib
Firm, flat surface with no pillows, bumpers, loose blankets, or soft toys
✓ Safe sleep dos
- ✓Room temperature 24–26°C in Singapore
- ✓Light sleep sack instead of blanket
- ✓Pacifier at nap and bedtime (after BF established)
- ✓Keep room dark - Use blackout curtains
- ✓White noise at 50–65dB helps newborns sleep longer
✗ Sleep hazards to avoid
- ✗Crib bumpers (suffocation risk)
- ✗Loose blankets or pillows in crib
- ✗Sleeping in car seat outside the car
- ✗Sofa or armchair feeding (fall-asleep risk)
- ✗Bed-sharing with exhausted or medicated parent

4 months regression
~2–6 weeksCause: Sleep cycles mature to adult-like patterns. The biggest and most disruptive regression.
Strategy: Introduce a consistent bedtime routine. This one is permanent - Cycles don't revert.
8–10 months regression
~2–4 weeksCause: Crawling, pulling to stand, separation anxiety. Brain is overwhelmed with new skills.
Strategy: Extra comfort, consistent settling approach, avoid introducing new habits you can't sustain.
12 months regression
~2–4 weeksCause: Walking, first words, nap transition from 2 to 1 nap. World is too exciting to sleep.
Strategy: Push morning nap slightly later; keep bedtime consistent. Don't drop the nap too early.
18 months regression
~2–6 weeksCause: Language explosion, toddler autonomy, molar teething. Separation anxiety spikes again.
Strategy: Clear, predictable routine. One extra book or song - Then hold the boundary. Firm but warm.
2 years regression
~3–6 weeksCause: Dropping the nap, potty training readiness, imaginative play causing bedtime fears.
Strategy: Keep quiet time even if no sleep. 'Monsters' need calm acknowledgement, not elaborate rituals.
Sleep Training Methods
Sleep training means teaching your baby to fall asleep independently. Most paediatricians consider it safe from 4–6 months. Five main methods suit different parenting styles:
| Method | Crying level | Speed |
|---|---|---|
| Extinction (CIO) | High initially | 3–7 days |
| Ferber / Graduated | Moderate | 5–10 days |
| Fading / Chair | Low–moderate | 2–3 weeks |
| Pick Up Put Down | Low | Variable |
| No Cry (Pantley) | Minimal | 4–8 weeks |
Night Waking: What's Normal?
Night feeds by age
Why babies wake (beyond hunger)
- Sleep cycle transitions - Lightest sleep at 45 min, 90 min cycles
- Sleep associations - Needs same conditions to re-settle
- Developmental leaps - Brain is too busy
- Overtiredness - Paradoxically harder to stay asleep
- Undertiredness - Not enough daytime activity
- Environmental - Noise, temperature, light changes
- Teething - Most pronounced from 4–30 months
Sleeping in Singapore's Heat & Humidity
Ideal sleep environment
- Room temperature: 24–26°C (air-con or fan)
- Humidity: 50–60% (dehumidifier if needed)
- Dress baby in single cotton layer - No swaddling if room is warm
- Use a light muslin swaddle for newborns if needed
- Keep cot away from direct air-con airflow
Overheating signs (act immediately)
- Sweating - Especially on back of neck
- Damp hair on back of head
- Flushed or red face
- Rapid breathing
- Restless, waking frequently
