I'd welcome any help with this! Our son is 4 and has been podding for just under a year (were using Animus before). For the last few months, we've started seeing crazy highs ("Hi") after pod changes, despite using a temp basal, which used to keep post-change highs away. The first big bolus after a pod change (usually a meal bolus) often seems to just disappear. 30-60 minutes after the meal, BG sometime shoots straight up as if there's no insulin in his system. Weird thing is, the correction bolus then works. Even weirder is that this doesn't happen with every pod change, though it's becoming more frequent - now happening almost once a week. (We do pod change every 2 days.) My husband and I are guessing that his young body is healing over the site quickly and that the first bolus disappears (somehow) as part of filling the cannula and breaking through the tissue. We could fix that by giving a sacrificial bolus after pod change - except that when pod changes are fine, this extra bolus wouldn't be needed, and we'd have to monitor carefully for lows over the next few hours. Has anyone run into this and found a cause? A solution? We might switch back to the Ping for a week or so (we still have supplies, and the pump is a year old) and see what happens, as we didn't have these problems with Animus set changes. Hoping someone has some nuggets of wisdom!
