Hi,
What worked for us in year one is this and so it will continue into year two:
We have a pencil case (red so visible, pencil case so not shouting "medical") that goes everywhere with S, carried by her teacher and transferred from one teacher to another if they are having a session with someone else. Everyone knows what it is and who it belongs to.
In it we keep her handset for the pump (Accu chek combo), finger pricker with some spare lancet drums, tub of strips, spare batteries for pump and handset, a few jelly babies in a bag and a 100ml bottle of lucozade also in a bag. The bottle I got from Boots (refillable cosmetics one) and I marked 50 ml and 100ml on it. I am also laminating some little cards with 'what to do if...' situations eg: 'if she is in the 3s treat with jelly babies, but if in the 2s treat with lucozade'.
In the classroom we keep a bigger bag (from yellow cross) which has a proper bottle of lucozade, spare cannula etc, spare finger pricker, care plan, box of breadsticks, glucogen, hypogel stuff, more jelly babies....
She wears her id bracelet all the time and doesn't notice it. My reasoning was that if we had an accident in the car and I was unconscious the paramedics would need to know it was her that was the diabetic and not me, since her kit bag would be in my handbag.
Each year I tweak it a bit, and just writing this makes me think we need a slightly bigger bag for carrying around, but not too big. eg, carrying the lucozade is a refinement after she went low at the far end of the school from her classroom and jelly babies just weren't raising her quickly enough. Hmmm, trip to WHSmiths I think....
