How does the toxic gas theory explain cot deaths which occur in adults arms?
If a baby has been lying in a cot or on some surface where he or she has been exposed to a lethal dose of toxic gas, and as a result the mechanism of death is already occurring when the baby is picked up, the baby can die while being held in the adult’s arms. Also, cot death can occur in an adult’s arms if a baby is picked up and held in an item of bedding which is generating toxic gas.
