Hi, Sorry to here of your little princess being diagnosed, It can be a big shock, with sadness and worry, such a lot to take in. My granddaughter was diagnosed at 2 1/2 years and has been a fine, she is healthy, getting on well at school and went to Nursery school for 3 days per week when she was 3, the staff had to be trained first in managing her diabetes before she could start. She had lots of support and is leading a normal happy life, she is 7 now <3
Take care and honestly, it will become less fraught and worrying and easier as time goes by.
All the very best to you and your little girl, RRB
