Sudden Unexpected Death in Infancy (SUDI) remains one of the most devastating experiences a whānau can face. While it is relatively rare, the impact on families and communities is profound. SUDI refers to the sudden and unexpected death of a baby under one year of age, including Sudden Infant Death Syndrome (SIDS) and fatal sleep accidents. Fortunately, research has shown that many cases can be prevented through safe sleep practices, careful monitoring, and education.

Understanding the Risks

SUDI can occur when infants are placed in unsafe sleep environments or situations. Risk factors include:

• Sleeping on unsafe surfaces such as adult beds, couches, or soft bedding.

• Sharing a bed with adults when certain safety conditions aren’t met, including parental smoking or alcohol use.

• Exposure to smoke during pregnancy or after birth.

• Premature birth or low birth weight, which can increase vulnerability.

• Overheating due to excessive bedding or clothing.

Safe Sleep Practices

The most effective way to reduce SUDI risk is to ensure babies sleep safely:

1. Back to Sleep – Always place your baby on their back to sleep, for every sleep, day and night.

2. Safe Sleep Space – Use a firm, flat mattress in a bassinet, cot, or wahakura (woven flax bed) with no loose bedding, pillows, or toys.

3. Room Sharing Without Bed Sharing – Keep the baby’s sleep space in the same room as caregivers for at least the first six months.

4. Avoid Smoking – Pregnant mothers and caregivers should avoid smoking, vaping, or exposure to second-hand smoke.

5. Keep Babies Cool – Dress babies in light layers and avoid overheating.

Additional Protective Measures

• Breastfeeding has been shown to reduce the risk of SUDI.

• Pacifier use at sleep time can offer protection, though it should not be forced.

• Immunisations support overall infant health and can reduce risks.
