I'm so sorry to hear of your little girls diagnosis, it is a big shock at first. In time, it will get easier with confidence and knowledge, that is why these forums are so good with helpful advice and support. My granddaughter was diagnosed at 2 1/2 and my GD and her parents took it well, I was the one in bits, she was extremely ill and in the HDU in hospital.
Children are tough little cookies and she will, I'm sure, not let diabetes stop her from having a happy and an active life.
Regarding starting school, or if she has already started, make sure the school knows of her condition and to get a care plan in place. Contact Juvenile Diabetes Research Foundation ( JDRF) they are a very good organisation and will be able to help you, my GD recieved a diabetic teddy bear called Rufus with coloured injection sites, it was a tremendous help :thumbup: Also you should be entitled to an allowance for your daughter as she has Type 1.
Try not to worry too much, take care.
With best wishes RRB
