Hi Julie,
I really do sympathise, i can remember taking about 1/2 just to coax Andrew to pull his trousers down for me to do an injection whilst his Dad held him, we then progressed to holding a sugar free ice pop to numb his leg for a few minutes with the provision that if he did it without a fuss he got the ice pop. In those early days there were many tears, screaming matches and hugs, for both Andrew and i, so you are not alone.
I cant get my head round your bs readings as there not what we use here, please forgive me, i'm having one of those senior moments, and can't remember the conversion bit.
Your not alone checking Lexie during the night and its only natural to want to do so, in the months to come you will find the confidence and reassurance that a full nights sleep for you both is possible.
Andrews body always wakes him and night hypos these days are rare, but when they did happen, his body always woke him as if he were having a nightmare. I usually met him on the landing and took his bs to find he was low, he would say he woke in a sweat with his heart pounding (like a nightmare) must be the bodies defence kicking in by waking him. Hope that puts your mind at ease slightly, its only natural to worry.
Low sugars can result in too much insulin, not enough food/snacks, too much exercise or not enough carbs to cover the exercise. In the early days they can result in the pancreas releasing insulin as the body is still in the honeymoon period.
Hope i've been of some help, keep asking the questions, i'm only too happy to help.
Take care,
Suzi x
