My 11 year old has just started secondary and I'm really struggling with his t time results all summer we have managed well unitl now when he comes home does a test at 5 and hes in the 20's never been this before.For example this morning when he woke got up at 7 he was 4.4 then he took 14.5 units of humalog 25 and lunch time he was 4.1 but by the time he got home he was 22.3.This has come as a complete shock to us has anyone had the same problems.
