Pediatrics 39 years experience
SIDS: The highest incidence is from 2 to 4 months of age and declines to virtually none after the first year of life. Remember always put the baby on its back to sleep. This also reduces the incidence.

CO2 retention: Although not accepted universally, the current theory regarding sids is the rebreathing of co2 which is normally exhaled with each breath by all humans. The idea is that sids is caused by the rebreathing of co2, in the prone position. Co2, which is a respiratory depressant, is rebreathed when infants inhale from a pocket of exhaled co2. This is why fans, and supine positioning is recommended.

What does sids (sudden infant death syndrome) have to do with smoking?

POISON!!: We don't know the exact specifics of what happens, but the statistics clearly show much higher rates of sids in parents who smoke. If mom smoked while pregnant, the toxins likely affect baby's respiratory center in brain and make it less mature. After birth, the poisons and toxins in the smoke, which can stick to your clothes, may affect the "switch" to tell baby to breath or affect the heartbeat.

Varioius reasons: Sids can be very devastating to a family, as you can imagine. Unfortunately, it is more of a symptom and does not tell you much about the cause. Here is link for some information about it: http://www.Ncbi.Nlm.Nih.Gov/pubmedhealth/pmh0002533/.

Is it possible that long qt syndrome can be the cause for sudden infant death syndrome?

Possibly QT: Sids is really just a term that means we really don't know what happened to your baby. It is indeed plausible that long qtc could be a cause, but it is certainly not the only one, because infants who have had ekg's for other reasons have gone on to die with "sids". Heart arrythmias are likely just one subset of things that may cause someone of any age to die suddenly. Be aware of family history.
