I can't figure this out, maybe because my sleep-deprived brain is addled: For the last three nights, my daughter's dinner-time number at 6 p.m. has looked pretty good, like 130. Then she goes high (275-300) around 7:45 or 8 p.m. We haven't been correcting these, assuming a post-meal spike. Then she crashes hard around bedtime, which is about 8:45-9, falling to the mid-50s. Her Dexcom traces look like a steep inverted v. Dinners have been relatively high carb but not otherwise unusual. I'm chasing my tail about what to adjust and which problem to tackle first. Any brilliant insights?
