Went to the playground for about 2 hours today. Used Dex and DS had a couple 60's from all the activity (confirmed with fingerpricks). Overall gave 44 g of juice and 12 grams of fiberone granola bar uncovered while we were there. Got home and he was 264 steady (confirmed finger).Corrected with our normal correction factor and he goes to watch cartoons with his brother. 1 hour later he comes to me and tells me, Dex says 61 double arrow down. Fingerprick is 38. Holy moly, I give him a juice box and he asks if he can eat. Scarfs down a bag of snack size chips (hey, it what he wanted). His only signs were feeling shaky and hungry. I have no idea how this happened....finger was clean, maybe the 264 was just an adrenaline type exercise high? So scary and I had glucagon ready to go.....I was so shocked he didn't have a seizure or something. This disease is truly crazy complicated unpredictable sometimes. Did I miss something obvious??
