My eldest daughter has really hurt her knee (fell over yesterday and managed to cut a three year old scar off her knee). I covered it today but she has gone to bed with bare legs to try and dry it out. What should I do tomorrow for school - she wears a skirt and tights (it's cold here at the moment). Should I put a dressing on it (too big for even a ginormous plaster), I a worried that tights will stick to her leg. Thanks (sorry if the detail is a bit yucky).
