Hi IHSUnfortunately for myself being diagnosed type 1 in the mid 60's just before my 11th birthday, I never woke up in the night to be able to treat a night time hypo so mum usually used her intuition, had one ear cocked and seemed to have a 6th sense to know if I was going low and get something sugary liquid into my mouth, massaged my cheeks and then as I came back to being able to mutter, then get me to drink some lucozade and eat a biscuit. I was usually dripping wet with sweat. I later found out that my alpha cells had been destroyed as well as my beta and this more or less stayed with me to this very day, so I for one understand why a parent checks on their kids in the night especially if they are not able to wake up to treat a low bg themselves.
Thank goodness for your mum's sixth sense. Like you my son does not wake up in the night when going low. I checked his bg once and he was 1.8mmol. Thank god I checked on him. Someone I know thought their child was stable overnight but had cgm for a week to help with daytime issues. They discovered that although her bg was fine at bed time she dropped to between 2-3 mmols after midnight and stayed there for hours. Her bg would rise to an acceptable level before she woke up and everyone was non the wiser.
