Why Safe Sleep Matters
Sudden Infant Death Syndrome (SIDS) and other sleep-related infant deaths are among the most feared risks for new parents. The good news is that evidence-based safe sleep practices can significantly reduce these risks. Understanding and following these guidelines is one of the most important things you can do for your baby.
The ABCs of Safe Sleep
Major pediatric health organisations summarise safe sleep as:
- A — Alone: Baby should sleep alone in their own sleep space.
- B — Back: Always place baby on their back to sleep, for every sleep.
- C — Crib: Baby should sleep in a safe sleep environment — a firm, flat surface in a crib, bassinet, or play yard that meets current safety standards.
Setting Up a Safe Sleep Environment
The Sleep Surface
- Use a firm, flat mattress — it should not indent when you press on it
- Use a fitted sheet specifically designed for that mattress
- The sleep surface should be free of inclines greater than 10 degrees
- Never use a car seat, swing, or bouncer as a regular sleep space
What Belongs in the Crib — and What Doesn't
| Safe ✅ | Not Safe ❌ |
|---|---|
| Firm, flat mattress with fitted sheet | Pillows or cushions |
| Baby in sleep sack or wearable blanket | Loose blankets or bedding |
| Baby in light, appropriate clothing | Bumper pads (including mesh) |
| Pacifier at sleep time (after breastfeeding is established) | Stuffed animals or toys |
| Room-sharing (not bed-sharing) | Wedges or positioners |
Room-Sharing vs. Bed-Sharing
Room-sharing is recommended for at least the first 6 months, ideally up to 12 months. Having baby's sleep space (crib or bassinet) in your room reduces SIDS risk while keeping baby close for night feeds.
Bed-sharing is not recommended by most pediatric health bodies, as it significantly increases the risk of accidental suffocation, entrapment, and SIDS. This risk is higher if either parent smokes, has consumed alcohol, uses sedating medications, or is very tired.
Temperature and Clothing
Overheating is a known risk factor for SIDS. Keep baby comfortably warm — not hot:
- Room temperature should be comfortable for a lightly clothed adult (around 16–20°C / 60–68°F)
- Dress baby in one more layer than you would wear
- Check for overheating: baby's chest or back should feel warm but not sweaty
- Avoid hats indoors during sleep
Building a Healthy Sleep Routine
A consistent bedtime routine signals to your baby that sleep is coming and helps them settle more easily:
- Bath (every 1–2 days)
- Gentle massage
- Feed (breast or bottle)
- Dim lights, calm environment
- White noise (optional but often helpful)
- Place baby in crib drowsy but awake — this helps them learn to fall asleep independently over time
Pacifiers and Safe Sleep
Offering a pacifier at the start of sleep (nap and bedtime) is associated with a reduced risk of SIDS. If you're breastfeeding, it's generally recommended to wait until breastfeeding is well established (around 3–4 weeks) before introducing a pacifier. Don't force it if baby refuses.
Final Reminder
Safe sleep habits should be followed consistently — at home, at grandparents' houses, in daycare. Make sure all caregivers know and follow these guidelines. Tired adults make mistakes; having these habits clearly established from the start makes them second nature.
