If a child (im talking 5 years old and over) doesn't blow their nose of their own volition then their parent or car giver should encourage them or facilitate them
(by giving them a tissue)
I spent some time with some relatives this weekend who's Dc are same ages as mine. Their oldest walks around with permenant green slugs dripping down to her top lip (nearly 6) and the youngest just coughs mouth wide open in any direction all the time with not a hand to cover her mouth in sight (nearly 5)
I know kids are GROSE etc. but seriously? What's the matter with teaching your children to have some basic hygiene and social skills?
Yuck.
