Mindingmum - I have allergy induced sinusitis and if i go anywhere that there is a plug in or other artificial air fresheners I get terrible sinus headaches and my nose starts to water, sneezing etc straight away. If I get prolonged exposure my sinuses get so bad that my eyes start to be gummy too like conjunctivitis.
SO GET RID!!!! (of the air freshener not your daughter lol)
I also use open window, hoover and damp dust, and if necessary (ie during potty training if a poo has been done in downstairs potty just as visitors are due a drop of lavender and geranium essential oils on a tissue on the radiator.
ooohhhhh shake and vac, how could anyone forget that sensation of highly perfumed talc being stuffed up the nose, as you hoover up a tub of that stuff
