Thanks all. At the time I was writing that I was massively stressed. It seemed like every day I came closer to getting them to take him back there was just one more barrier.
I know in the long term we'll be able to match his insulin to what he chooses to eat, but in the short term while we and he and the school and after school club all learn to cope, the nurse recommends three meals and three snacks a day. The meals - breakfast, lunch and dinner with exactly 75g carbs and the snacks - mid morning, mid afternoon and bedtime with exactly 15g carbs - the level his levemir balances out so no extra injections needed.
As a very busy working mum who previously relied on school dinners, switching to preparing carb counted breakfasts and packed lunches as part of the already crazy morning routine has been a really tough transition. I'm exhausted from having to wake up earlier every day. I wanted the morning and afternoon snacks to be simple "grab and go" in this early phase - sufficiently healthy, but also something I could grab at 8:15am while yelling "where are your shoes?" And "can you remember how to spell subtle, it's your spelling test today?" And "here's your packed lunch where's your pe kit?"
The nurse recommends cereal bars. Which seemed the perfect solution. Until I found they were "produced in a factory which also handles nuts".
So that's the explanation- other parents may identify with this. My moaning post was because the afterschool club kept changing what I had to do to let him go back to there and my boss kept adding more to my work to do list, to make leaving work at 3pm rather than 6pm ever more complicated. The nuts in the cereal bars was a "last straw" rather than a big deal in and of itself.
A couple of weeks on and I wish I could say it's got easier. Maybe it has in some ways. But I do feel absolutely exhausted
