Hi,
We too have a constant struggle with both my girls' HbA1c's, so I relate to how fed up you're feeling
.
Just a thought - do you know if your daughter goes high during the night? We didn't realise what a problem this was until my daughters went on continuous blood glucose monitoring devices over several days and nights. They both regularly went into the 20's in the early hours and then often dropped again by morning so we did not realise it was happening on a regular basis. It is v difficult to get good HbA1c's if this is happening, as no matter how hard you work at it during the day, the nights cancel out yr hard work.
If you don't have access to a continuous blood glucose monitor thru yr hospital, you could try doing some tests during the night over 2 or 3 nights yrself - exhausting I know, but it may give you some useful info that the consultant could use to adjust insulin doses.
