Hi Laura,
Welcome to the forum.It's not easy getting your head around a diabetes diagnosis when it's yourself but I can imagine when its your child, it's even harder. As Mums we just want to protect our children and when you can't, it's very difficult. As others have said, there are quite a few mum's of diabetic children on the forum, so I'm sure they'll give you heaps of advice and supportive words.
The fact you have tried to learn as much about this condition as possible, shows what a caring mum you are, so stick with us and I hope you'll soon feel welcome and confident in asking any questions you might have.
All the best, chocoholic.
