A few days ago our son went low at school after breakfast (very unusual). We cut his basal and afternoon bolus and he went low again. I intentionally under-covered dinner and he headed out to an evening baseball game. It took two 20g gatorades during the game to keep him above 100 (not a very strenuous sport). That night we cut his basal off for an hour then cut it in half for a couple hours and we still couldn't keep him above 100. I've cut his basal 35% the whole next day and he still kept going low. At bedtime, he took in two tabs and a juice box and we couldn't get him above 105. Last night, after basal cut in half for most the day, I gave him a juice box and two bon bon's (14g) and that's what it took to get him above 110. Last night, dinner bolus 25% reduction, basal cut off completely for two hours, juice box barely kept him above 80, so followed with another juice and 20g snack. That spiked him to above 250. We gave small correction and with a reduced nighttime basal rate he drifted down to 120 by morning (we usually get "stuck" when above 225 or so). Anyway, we're into our 9th month, he's progressively needed more insulin over the past five months or so, and then this. I thought his honeymoon ended months ago when his nighttime highs quit drifting down on their own. He's not sick. Is this a honeymoon recurrence of some sort? Or just normal ups and downs of a 9.5 year old boy? The sudden insulin sensitivity just seemed pretty severe and sudden. Thanks.
