Hi Gaynor
Firstly I am not a parent of a type 1 (I have it) but I have a 4 year old who has just started school and has a problems (toilet type sorry if TMI) and I know what a worrying time this can be.
Re the early mornings - I was diagnosed in April and still haven't resolved this yet myself but what has been recommended is a protein snack (cheese / meat) before bed - if can help stop the dawn effect if that is what is happening - it might be worth a try.
The readings at 10am could be a number of things - is this 2 hours after breakfast if not that could be making a difference. Stress could also be having an impact, it may be worth waiting a couple for weeks more to see if it settles if this is vastly different from the reading you were getting at home. For example I did an exam in July and even though I woke up ok ish, by the time I sat the exam I had gone up to 16, 2 hrs into the exam I was 8 and when I finished I was 5.9 so emotions can have a big impact. Is he walking to school that could also be having an effect - my figures go up when I excercise - especially in the mornings for some reason?
It may also be that his honeymoon period has come to an end. Personally as far as changes go I have been told not to change my lantus (slow acting one) without checking with my nurse and if he is going low over night this would make it worse (Have you tried checking what he is at night - say at 1am ish - I know that is what some people do?). You could try giving him a little more novorapid in the morning and see what happens, certainly don't change both at once.It may well be that he may just need to settle into his new routine a bit though.
I know what you mean about feeling like it was sussed and then..... that is how i feel and I think going by what other people say on here this is just something that we have to keep reviewing.
Hopefully some of the other mums for t1's will be able to answer better than I have. :?
All the best
