Measure blood sugar and insulin
Measure, read the value, dose the insulin: several exact stages where a single skipped step feels frightening for child and adult alike. With the whole chain laid out as pictures, no one has to hold it all in their head. Follow the steps below.

About this visual support
What makes this routine demanding isn't a single stage but how many there are and how exactly they hang together. The measurement gives a value, the value governs the dose, and the dose has to be right. A forgotten or swapped step doesn't feel like a small mistake but like something dangerous, and that feeling presses on the whole situation.
Visual support relieves the memory by placing the entire sequence outside the head. When each step has its picture in fixed order, what's done and what's next become visible, and you can double-check calmly before the insulin is given. The child also gets a chance to learn the order gradually, one step at a time.
A concrete tip is to colour-code the two phases differently, one colour for the measuring and another for the dosing, so the boundary between them is clear and no one starts dosing before the value is read.
To have the same controlled order every time, you can build the sequence in the Routined app and tick off the steps one by one as you go.
