Hi
Just a little thought...
Don't worry yourself frantic, like Harry says (very good advice Harry!) take it a step at a time.
You will find that night-times will settle very quickly in reality. It sounds as if you really have some excellent knowledge around the pump already with altering basals. If levels go as high as they spiked, then you could raise the temporary basal rate to drop levels a little quicker, but only be sure to do this if Dylan can be closely monitored, and if levels are above 15, then as soon as they lower bel0w 9, turn off the higher temporary basal rate to avoid crashing out. Like Lily, I too can go to bed on 6.0 and still be at 6.0 in the morning and at 3am when I have tested. It is only an odd occasion when this will not be right, but in my case I will wake up higher, rather than suffering low's like I used to. You will soon have mastered the night times, and you will both be able to sleep!!!!
The only other thing to watch out for is, if Dylan's levels raise or drop within 2-3 hours of eating food, then this may be down to the bolus/carb ratio being too high or too low, especially with any exercise....
Also makesure that you write as much detail in log books regarding exercise and food and reactions as possible, refering back does sometime come in handy.
You are doing fantastically, be so proud of yourselves. It is a totally different regime to get used to, and to be managing it so quickly you both really deserve to give yourselves a huge amount of credit and really, really proud. It is so wondeful to see Harry so comfortable with Lily and her pump too so very quickly. It is absolutely fantastic to read your postings from the pair of you, because you are so switched on to mastering it all. I just think it is so fantastic to read...despite the occasional plea of help-it is so great to read of the control that you both have achieved......Bl**dy brilliant!!!! Well done
