My kids are definitely showing symptoms (different within each child). I live in fear of anyone giving my eldest a fruitshoot as she becomes horrific but apart from a distinct fear of anything coloured orange I haven't a clue what else to avoid. Could mumsnetters put together a list of things I should avoid to prevent a)teenager from hell in my 9 year old and b) whirling dervishes in the 5 and 2 year olds.
