Hello Fenn
Sounds like your ratios might need adjusting. Most people find they have a 'honeymoon' period where they need less insulin, but as time goes by they need a bit more. Ask your diabetic team to help you learn how to change it yourself, your family will help you out with this I'm sure. After a bit you'll get confident about how to make adjustments as your ratio will not stay the same - my son's was always changing at first, and still does. Your blood glucose records will help with working out how to change things.
