Hi Jossy,
Well done for finding this forum so soon after diagnosis! It took me a lot longer but the support and advice and understanding that I have found here has helped so very much!!
You have already had some great advice - the Children with Diabetes crew are priceless in terms of support for you, your boy and your non diabetic kids. This condition will effect all of you and you don't have to find all the answers yourself.
The next few weeks will be an intense learning curve and you are about to learn a whole new language. Anything that you don't understand or feel comfortable with, please ask questions. And remember that this is not your fault - diabetes can be a random and unexplained hitchhiker. Just get your boy through the adjustments and we will help where we can.
I have two T1 boys aged 10 and 15.
Take care, Ange
