DD went to bed at 11:30 pm, blood sugar 135. Not because I was expecting a problem but because this is what we do, I measured 70 minutes later when I was going to bed. Blood sugar 38! Gave her about 18 g of juice, and measured again 20 minutes later - now she's 56. Gave her another 18 g juice, as well as 25 g of cereal and yoghurt - will be testing again shortly. This came quite unexpectedly. We've been challenged lately by puberty-type fluctuations and overall higher blood sugars - so we had increased the Lantus a few days back. She was on the low side last night, so we dropped Lantus by a unit today. Obviously that wasn't enough. Let me just say I'm very thankful that we test nights. There are so many tests on so many nights where she's fine and one could say it was a waste of time measuring. But then there's a night like tonight where you catch a bad and unexpected low - and it is all so obviously worthwhile. I can not believe that there are medical professionals out there who say that Type 1 kids don't need to be tested at night..
