Hello,
My son was diagnosed 4 months ago and for the last week and a half he was having no insulin at all. He was on a permanent low and this was when he was just on 0.5 levemir so took him off that and was ok until the last couple of days with sudden high blood reading of 21 with ketones of 1.2, I amediatly gave him 0.5 nova rapid and within half hour his bloods were 3.7 obviously feeling very ill. Poor little man. Unfortunately they are just very very sensitive to insulin and take a bit longer to work things out. It does generally take over 6 months anyway but it may take a while longer for our children to find reasonable levels. Dont be surprised if he ends up on none but I did wonder if he even had it but they do and I have experience other parents wondering the same thing.
Hope this helps, anymore questions feel free to ask.
