Hi Kiera, welcome to the forum
🙂 Really sorry to hear about your little one's diagnosis

It can be an awful lot to take in, in a very short time, so no wonder you are feeling so overwhelmed!
😱
What insulin is he on, and how has he taken to the fingerpricks and injections? I would highly recommend getting a copy of
Type 1 Diabetes in Children Adolescents and Young People by Ragnar Hanas. It's not cheap, but you will find it a massive help in understanding things and what the medics are saying, plus it can help reassure you and help you find the right questions to ask at appointments. I hope you are getting good support from his healthcare team.
You might also like to read
Adrienne's essential guide for parents of newly-diagnosed children which will hopefully help you understand how YOU are feeling about everything. JDRF, the Type 1 charity, provide a
free 'KIDSAC' for newly-diagnosed children, which includes a Rufus Bear to help him with injections.
Please feel free to ask any questions you may have - no question is considered 'silly', so if it is bothering you or confusing you, just ask! There are lots of friendly, knowledgeable people here who will be more than happy to help, so don't ever feel you are alone in this or have no-one who understands.
