If Dylan is going low at 8pm, what time is he eating and having his bolus before that low?
You can probably see by now that although he was 4.2 at 10pm his levels went quite significantly upward. If this occurs again, personally I would hold off 30 minutes and do another test before giving another quick acting food.
You need a night without any high's or low's at least 5 hours before hand to really establish what is happening with Dylan.
I have a feeling that possibly his carb ratio needs tweaking at tea time, and his basals may well need to be raised a little during the night.
Saying this, don't forget that if Dylan is high or low at any point due to his basals-it is 3-4 hours before hand that you need to alter the rates for, right up to the hour where the high or low is occuring.
It is so much easier to sort out high's than low's initally if they are high's due to actual bloods and pump. If the high's are due to rebounds from hypo's you don't really get to see the true picture of what is going on.
You are so early in to the change over, and it is such a hugely different regime, you have to congratulate yourself that you are so confident and adept at handling the pump so quickly.
Also, I was reading John Walsh's book last night, and the amount of quick acting to get a person out of hypo, according to him can be scaled by body weight. It may be that Dylan being so young and small compared to us adults that he actually doesn't need the standard gamount of glucose (jelly babies, M&M's etc) to raise him up....
You are doing best keeping Dylan out of hypo land, but until you can alleviate the low's 5 hours before going to bed, I think it will be slightly difficult to find out truly what is happening at night. It would be better to cure the low's before bed to ascertain what is happening during the night.
