A bit more information on
hypo unawareness. An important addendum, the normal hormone response to low blood sugar is not present in hypo unaware individuals i.e. the problem is not being able to notice the symptoms but not having any symptoms at all.
The decision to lower his doses to let him run a bit higher for while is generally a good idea to restore hypo awareness, although the effectiveness will depend on what's causing the hypos (ask the consultant if it is possible to get a continuous glucose sensor for a week to pinpoint that).
Generally, if blood sugar is low after meals then the meal time insulin doses will have to be reduced; if pp blood glucose is OK combined with a pattern of lows then the basal dose will have to be reduced; finally, if physical activity ("adventure") leads to hypos then he'll either have to have snacks during such activity, or get an insulin pump (insulin release is reduced during physical activity in healthy people, which obviously cannot be achieved with ideally constant basal insulin)
Carb counting is useful - it allows one to eat more variable meals - but will not really solve the hypo problem. It might, in fact, be easier to stick with fixed meals until you can work out an insulin regime that will not result in frequent hypos. This can then be used as a starting point for carb counting (knowing how much insulin you need for the fixed meals allows you to work out how much you need for larger/smaller meals).
Whilst there are special scales with pre-programmed nutrition information for common foods I don't really think that there's much point in getting one (you'll still have to look up the codes for the food, rather than just being able to look at the label on the box).
As for the teachers, since your child is able to do all the testing and injections, I think that a fairly simple checklist would enable any teacher to supervise your child.
- Check BG before meals; if it's OK take X units of insulin, if it's high increase by Y u, if it's low decrease by Z u.
- Check after meals; if it's OK do nothing; if it's very high, give a correction dose of X u, if it's low give a snack.
- Check before physical activity, give a snack if not high
- Etc
