Scary low sugar night

I can't even record what his sugar was tonight. Luckily Mike is OOT and Ian decided he wanted to sleep with me. We do a bit of musical beds in this house ;) I was sleeping lightly but awoke by a noise. Felt him as I do all night when we r together and he felt very off. Extremely sweaty but cold. Signs of entering into shock. I immediately got the kit and took his reading. He was 85. It's a bit chilly in here and he's under a down comforter and sweats easily so I thought maybe id wait a min before taking it again. Adjusted his covers and kept feeling him. Wasn't getting better. I grabbed the kid to do another test. I was trying to keep it mellow with a flashlight to try not to wake him. Which was t the best idea. Did 2 more readings and neither worked. By now he was irritated so I decided just to treat him. Got a banana and some peanut butter and gave it to him. He then asked for a cookie. Which I happily obliged. Took him a bit to fall back asleep but within 5 minutes he felt normal again. Just like in the hospital that first time. So quickly sugar balances him out. It's surreal. I def need that dietician cause clearly what I'm doing is not working. It was only midnight. Can't imagine if I wasn't with him what he'd be like by 7am. Scary!
