SIDS & Safe Infant Sleep
SIDS is the unexplained death of a sleeping infant under 1 year, peaking at 1–4 months. Safe sleep teaching is how nurses prevent it.
What SIDS is
An unexplained sleep death under 1 year
Triple-risk model: SIDS occurs when a vulnerable infant (impaired arousal or cardiorespiratory control), in a critical developmental period, meets an outside stressor such as an unsafe sleep environment.

Tummy time or prone sleep?
Same position, opposite safety — it depends on awake vs asleep
| Tummy time | Prone sleep | |
|---|---|---|
| Infant is | Awake, watched by an awake adult | Asleep |
| Safe? | Yes — every day | No — place supine for every sleep |
| Why | Builds motor strength, prevents a flat head (plagiocephaly) | Prone and side-lying sleep are unsafe |
Teach your patient
Swaddling does not lower SIDS risk; infants usually start trying to roll at about 3–4 months. Once the infant rolls both ways unaided, they may stay in the position they roll into, but every sleep still starts on the back. A wearable blanket (sleep sack) can replace loose blankets; never weighted sleepwear or blankets. Products marketed to reduce SIDS and home cardiorespiratory monitors have no proven benefit.
Alone, on the Back, in a Crib — firm, flat and bare, in the parents' room. Side-lying is never the safe middle ground, even with reflux.

SIDS & Safe Infant Sleep
Sudden infant death syndrome, or SIDS, is the sudden, unexpected death of an infant under one year old that stays unexplained even after an autopsy and a full investigation, and it usually happens during sleep. Risk peaks between one and four months, and more than ninety percent of these deaths happen before six months, so teaching starts before discharge. Remember the ABCs: alone, on the back, in a crib. That crib is firm and flat with only a fitted sheet, with no pillows, bumpers, blankets, positioners, or toys. Side-lying is not safe, and that includes infants with reflux. Room-share without bed-sharing, ideally for at least the first six months, and never fall asleep with an infant on a sofa or armchair. A car seat or swing is not a bed. Offer a pacifier at sleep, but wait until breastfeeding is well established. Breastfeeding and immunizations lower risk, while smoke, alcohol, drugs, and overheating raise it. Tummy time happens only while the infant is awake and watched. If a family loses an infant, support them without blame.
