SLF speaking here - interesting point in the report: "Before he had children, the FO's normally slept 8 hours per night. After having children, the FO normally slept approximately 6 to 7 hours per night, between 2300 and 0600, which could often be interrupted when the children required care."
As a father of two myself I remember those days - is that a hazard? Also, given a family situation where the wife maybe not feeling fully supported by the husband who is away often could there be an addition danger from those settings. Just a thought?
