We fairly consistently experience lower than usual BG after a site change, for at least a few hours. We manage it by testing more frequently and, if in the evening, using a temp basal at bedtime to be conservative. I'm wondering if anyone else experiences this? Is there a "formulaic" way (i know, ydmv!) that we can address with a temp basal? I searched but only found posts about CWD going high after a change. Tonight, for example, DD was 80 at bedtime despite being given insulin well after her dinner... manageable but frustrating and energy-zapping for us. We gave her juice, and now I know she'll be 250 at her next check. Sigh. DD is 3.5 years, 1 year post dx, and pumping on medtronic mm with mios since April.
