Hi Elliesdad,
It does get better, really it does! My younger daughter was diagnosed at two and a half, her older sister at eight (the year before). It's really horrible at first and such a steep learning curve, but you will get accustomed to it all much sooner than you think, simply because you have no choice.
If Ellie is hovering around hypo a lot of the time let her sip on a sugary drink, or have some sugary ice lolly - whatever it takes to keep her out of a hypo and hydrated.
Any questions just ask and we'll all do our best to answer. Hang in there!
Best wishes,
Sue
