He has them once every couple of weeks, they ALWAYS come home stinking of cigarettes.
Dd has recently been diagnosed as asthmatic, I've brought this up with him several times, if I do it face to face he tells me to fuck off, if I say it over email or message there's no response.
He's generally a pretty half arsed parent, but I can deal with a bit of benign neglect one day a fortnight, I can't handle the health implications for my dc with him smoking in the same house as them, or right beside them when they are out walking (cigarette burn in dds jacket close).
Is there anything I cam actually do, that doesn't involve appealing to his better nature, as he doesn't seem to have one.
