I also agree that he might need a little more insulin before he's ready. I want him to be totally ready and after these past couple of days, I was thinking we might be heading towards that. We'll do our best to administer one drop if he's in the green at test time or maybe 95 or higher.
I just did some test measurements into the sink to estimate 1 drop. When I dosed it up to the 0.1 we were giving, I got 1 drop to come out and another teensy tiny drop, but only after serious plunger pushing. I imagine Johnny wasn't getting that little bit, right? Makes me a tad nervous that he was already down to a drop. But I tend to worry about something in most situations, so that's probably the detail my brain picked for tonight.
Then, I thought it might be easier to gauge by dosing it up to 1.0 unit and see how many drops came out. I got three. Does that sound right? I anticipated more, but they were bigger than the drop from the 0.1. I just don't know how you decide what 1 drop is...it seems relative to what you dosed up first. Sorry to be such a worry wart. It runs in my family!
ETA: Thanks for the link to Raja's spreadsheet! I've been looking through some OTJ kitties trying to find a chart that reminded me of Johnny's. Very similar! I hope we have as great of an outcome.
