I have been googling carrot lapel pins - have far too much time on my hands with this foot injury. 
I reckon I could knock some up for pennies using fimo and brooch findings - could even get ready made polymer carrots off ebay for a couple of quid.
What do you think - shall I make some?
I'd be happy to do it - it would give me something else to do while I'm sitting here with my leg up!
Lisa, the carring carrot thing came about because someone, sorry I've forgotten who, had some spectacularly patronising advice from a member of staff at her dc's school, about 'fixing' his speech issues by making him some carrot sticks - including how to make them - in considerable detail.
Since then, anyone who offers patronising advice to any of us, suggesting things we couldn't possibly of thought of ourselves 
to do to support our dcs development (eg zzzz's sister telling her that all she needs to do is read to her dcs every day) earns the title 'Caring Carrot'.
It can often be applied to well-meaning, yet clueless professionals who seem to think that we could fix our dcs if only we were better parents.
