Sorry to have been awol. I feel like I am falling off this thread but really don't want to. I think I really need to evaluate the whole food thing because its just not working. I am completely at a loss. 
But you guys are all doing amazingly 
GT - really good luck for your interview, I am trying to think of any sort of question that may come up..I would imagine questions on the following are possible
Confidentiality because of this court case recently
Equal opportunities - how do you ensure fair play for all?
Child protection - what happens if a child makes a disclosure you to, or you hear or witness something - what do you do? ( Talk to your class teacher, make factual written statement etc. Can you read their policy before? )
Anything to do with bullying, problems arising during wet play, how best to mediate in a dispute? ( This is only what you do as a mum with your own DC ) What would you do if a child made a racist comment?
Are your first aid trained GT? This is something you could be proactive and say you are keen to do and this would enhance your status.
Classic ones - what do you enjoy about working with children? What would you bring to the job ( a warm coat and sense of humour!) Can you describe a game you could organise?
Why do you want this particular job? How will you be impartial with your DC there to?
Do you have any questions ? Think of something relevant - maybe something about training e.g. first aid?
Maintain eye contact, smile, be upbeat and enthusiastic, firm handshake whilst maintaining eye contact, thank you very much blah blah. Gimme the job.
Really sorry Pretty, sad times.
