We are one week into pumping....and things are going relatively well, but highs and lows are responding a bit different on the pump. Lantus dose before the pump was 3 units/once day/PM. Our suggested start basal rate was 0.100 u/hr. We had so many lows the first 24 hours we had to decrease it to 0.025u/hr. Well, that worked perfect for 3 days. Then, DS was waking up above 200 and pretty much staying there all day?? and so we increased gradually to 0.075 and we have better in range numbers again. Throw in more variables like swimming, playing with friends on summer evenings and here we go with no true lows.....but around 80-104 at bedtime and about the same before dinner (about 4 hours post lunch). Fingerstick at 104 3 hours post dinner, we treat with 8 grams of "fast sugar," and then retest in 15 min. He's gone down to 80 (fingerstick). Okay, gave 5 grams of greek yogurt with a dab of honey. Retest in 30 and we're 240 and have been steady there for 2 hours. Ugh, now I'm going to have to correct again or I could increase basal. I'm going to go batty, feels like I'm chasing numbers much more than on MDI. I think the ability to tweak basals in less than 24 hours as an option is a steep learning curve for us! So, any general guidelines on treating lowish numbers with carbs or just decreasing basal for a short period of time? Our CDE said people do both.....mentioning specifically that some teens will suspend basal vs. treat a low with food bc they want to avoid consuming extra calories. And, honestly, sometimes our DS is sick of "eating on demand" for a lower number. I can't blame him!
