So excited we got dex today!! My daughter is not TOO crazy about it because the humongo inserter. But it's pink so she'll get over it. Anyway, any advice for making it last longer/ be more accurate? Is it true that you cannot insert it vertically? I would think people wear itvertically on their arms, no? She doesn't give me too much of an issue with things (except comfort sets awhile ago, not a fun time in my life) so I don't think getting it in will be an issue. I've watched a youtube video and will do it again tonight. Should I wait til her insulin from dinner has worn off and it's just basal working or can I calibrate it while her food and insulin is still working?
