Hi Chuck,
My son Andrew was diagnosed too when he was 7, and he'll be 10 on Mon. He didn't like needles either, but honestly who does! We spent about 3months using a sugar free ice pop to numb his leg a little, then if he didn't make a fuss had the ice pop as a reward. Eventually after a year and a half we sent him to a diabetic holiday camp for five days and he came back doing them himself, even sent me a postcard telling me of his accomplishment, i was so proud i cried!
We still have the days where he hates injecting and recently bought Elma cream, bit like magic cream and numbs the area, though takes a bit of time to work. This is a great site and you will learn plenty, only wish i'd found it sooner.
Any advise you need regarding schools ect, theres plenty to help you, as for Halloween, let her go trick or treating if she's well enough and then divide her goody bag into a treat jar for hypos or for use before activities ie swimming ect, then fruits and nuts which she'll be able to eat as snacks.
Take care,
Suzi x
