Sudden Infant Death Syndrome (SIDS) — Prevention

The topic of SIDS is frightening — and that's understandable. It is every mother's and father's deepest fear. But: the risk has decreased by over 90% in recent decades because we now know how to protect our babies. This article doesn't aim to scare you, but to give you knowledge and confidence. You can actively do a lot to protect your baby.

Posibles Causas

  • 1Triple-risk model: interaction of 1) vulnerable baby (e.g., premature, brainstem immaturity), 2) critical developmental phase (2-4 months), 3) external trigger (prone sleeping, overheating)
  • 2Sleeping on the stomach — the most important preventable risk factor
  • 3Smoking during pregnancy and after birth (doubles to quadruples the risk)
  • 4Overheating: too many blankets, room too warm, hat during sleep
  • 5Soft surfaces, pillows, stuffed animals, and cot bumpers in the bed

Qué Puedes Hacer

  • BACK to sleep — ALWAYS, for every sleep, including daytime naps (Back to Sleep campaign)
  • Sleeping bag instead of blanket — no pillow, no stuffed animals, no cot bumpers
  • Own cot in the parents' bedroom (room-sharing, NOT bed-sharing) for the first 6-12 months
  • Smoke-free environment: nobody should smoke in the home, not even on the balcony before cuddling
  • Room temperature 16-18°C for sleeping — check neck, not hands/feet

¿Cuándo Consultar al Médico?

  • Baby has an ALTE (Apparent Life-Threatening Event): colour change, floppy muscle tone, breathing stop → call 911/112 IMMEDIATELY
  • Baby breathes irregularly with long pauses (more than 15-20 seconds) → inform paediatrician
  • Sibling was affected by SIDS (slightly increased risk) → monitoring and counselling with paediatrician
  • Premature baby born before 37 weeks → discuss special precautions
  • Baby sweats heavily during sleep and seems overheated
  • IF YOU ARE WORRIED: Trust your instinct. Better to call the paediatrician one time too many than one time too few

Notas Según la Edad

Highest risk: months 2 to 4 of life. 90% of all SIDS cases occur in the 1st year, most between months 2 and 4. From month 6 the risk decreases significantly. After the 1st birthday the risk is very low. BUT: Prevention measures apply for the ENTIRE first year. In Germany about 120 SIDS cases still occur annually (vs. 1,300 in the 1990s) — awareness campaigns are working.

Preguntas Frecuentes

Can my baby sleep in my bed?
Official guidelines advise against bed-sharing (baby in parents' bed) as it can increase SIDS risk — especially if a parent smokes, has consumed alcohol, takes medication, or is extremely tired. ROOM-SHARING (baby in own cot next to the parents' bed) is the safest option and is recommended for the first 6-12 months. If you breastfeed and practise bed-sharing, familiarise yourself with the Safe Sleep Seven guidelines.
What if my baby rolls onto their tummy at night?
Once your baby can independently roll from back to front AND back again (usually from 5-6 months), the risk is significantly lower. ALWAYS place your baby on their back — but if they roll over in their sleep on their own, you don't need to turn them back. Make sure the cot is free of loose items.
Do monitoring devices (breathing mats) help?
Breathing monitors and sensor mats may provide peace of mind, but there is NO scientific evidence that they prevent SIDS. No monitor replaces the proven prevention measures (back sleeping, sleeping bag, smoke-free, correct temperature). If a monitor helps you sleep more calmly — use it. But don't rely on it exclusively.
I'm so afraid of SIDS — is that normal?
YES, this fear is completely normal and shows how much you love your baby. The vast majority of babies sleep safely, and the numbers continue to decrease. Focus on what you CAN do: back sleeping, sleeping bag, smoke-free, cool room, own cot in your room. If the anxiety overwhelms you and affects your daily life, talk to your midwife or doctor — that's not weakness, that's strength.
