Never the less BW is right in that a little boy of 7 will always sniff and swallow. My imprecations that when he coughs he should spit go against everything he is taught by his mother and the school ... ie Spitting is rude, nasty and naughty. That, when coughing up phlegm, one should dispose of the resultant mouthful discretely into a tissue or down the WC rather than swallow it is not an option that he will consider. None of this is helped because the 14YO Hormone Heap stands there with a look of distaste on her face muttering "Gross!" the whole time
