Why Safe Sleep Matters

Sleep is essential for a newborn's growth and brain development — and creating a safe environment for that sleep is one of the most important things a new parent can do. Understanding and following current safe sleep guidance helps protect your baby during their most vulnerable months.

The ABCs of Safe Sleep

Safe sleep guidance is often summarised as ABCs:

  • A — Alone: Your baby should sleep alone in their own sleep space
  • B — Back: Always place babies on their back to sleep (not side or tummy)
  • C — Cot (or crib/bassinet): Baby sleeps in a safe, flat, firm sleep surface

These principles are widely endorsed by health organisations and are associated with a lower risk of Sudden Infant Death Syndrome (SIDS).

Choosing the Right Sleep Space

Not all baby sleep products are created equal. When selecting a sleep space, look for:

  • A firm, flat mattress that fits snugly in the cot with no gaps around the edges
  • A fitted sheet designed specifically for the mattress size
  • A cot, crib, or Moses basket that meets current safety standards in your country

Avoid products marketed for sleep that are inclined, padded, or nest-like (such as sleep positioners or loungers) as these are not considered safe sleep surfaces for unsupervised sleep.

What Should (and Shouldn't) Be in the Sleep Space

✅ Safe to Include ❌ Avoid in the Sleep Space
Firm, fitted mattress Pillows or cushions
Single fitted sheet Loose blankets or quilts
Baby sleep bag (appropriate tog) Bumpers or cot liners
Dummy/pacifier (after breastfeeding is established) Stuffed animals or soft toys
Sleep positioners or nests

Room Temperature and Clothing

Overheating is a known risk factor for SIDS. The recommended room temperature for a baby's sleep environment is generally between 16–20°C (61–68°F).

A simple guide: dress your baby in one more layer than you'd feel comfortable in. Sleep bags with an appropriate tog rating (based on room temperature) are a practical way to keep baby warm without loose bedding.

Check for signs of overheating: sweating, flushed cheeks, damp hair, or rapid breathing. Feel baby's tummy or the back of the neck — if it's hot and sweaty, remove a layer.

Room-Sharing (Not Bed-Sharing)

Current guidance from most health authorities recommends that babies sleep in the same room as a caregiver for at least the first six months — but in their own separate sleep space. This makes night feeds easier and has been associated with a reduced risk of SIDS.

Bed-sharing (sharing a bed with your baby) carries specific risks, particularly with certain factors such as parental smoking, alcohol or medication use, or extreme fatigue. Speak with your midwife or health visitor to understand the risks and safer alternatives if bed-sharing is something you're considering.

When Babies Can Sleep on Their Tummies

Once your baby can roll from back to tummy independently and consistently, you don't need to roll them back. However, always start them on their back for every sleep until they roll themselves. Supervised tummy time while baby is awake is still important for development.

A Reassuring Note

Safe sleep can feel like a lot to navigate when you're already exhausted. Take it one step at a time, ask questions at your health visitor appointments, and remember that doing your best with the information you have is exactly enough.
