Welcome to the forum Gemma, sorry to hear about your diagnosis. My son is type 1, nearly 16 now, diagnosed aged 4. If it's any reassurance, he has never had an episode of DKA, despite BG levels soaring into orbit sometimes. As long as you are checking your BG regularly, you'll pick up on an out-of-range number and be able to take action (ie snack for low, insulin for high) and bring it back into line.
The riskiest times have been whenever he's had a vomiting bug, as this is quite hard to manage with type 1, as you can get low BGs with high ketones. Unfortunately young children are bound to pick up these bugs at playgroups and school, and having young children yourself means you might also catch them. I estimate I caught about 1 in 3 of my son's tummy bugs

. So (not being a prophet of doom
🙂 ), I've attached a really helpful link below if you ever find yourself trying to manage this type of illness. Ask your DSN for a blood ketone meter if you haven't already got one - ketones should be checked whenever you are ill or if you have a persistent high BG that hasn't come down after an insulin correction.

Do get yourself a copy of the Ragnar Hanas book, it's the bible of type 1! It's a big learning curve but you'll adapt very quickly don't worry.
