Hi Anne,
I have 2 daughters with Type 1, now aged 14yrs & 7yrs, they were 8yrs and 2 yrs respectively when diagnosed. It is very hard at first, such a worry and a very steep learning curve for you all. It does get better with time and you all adjust. Try to take things one day at a time. It sounds like you have a lot of support from the diabetes nurse which is great, not everyone gets that!
As for school, we have found that by and large the other kids accept it. Occasionally we have had problems, but not often and the schools have made sure the children understand why extra snacks sometimes need to be eaten etc.
If you have any questions, ask away and one of us will try and help you. Or feel free to PM me if you would rather.
Best wishes,
Sue
