The dance is tonight, and her bg reading have been roller coasting. Up and down, I am a bit stressed at her being at the dance. So many chronic lows, mostly 40 to 50 range. I lowered all of her basals, downloaded the pump stats. Then ran a temp basal of -30%, lowered ISF, and I:C ratios. Still getting lows and now a stubborn rebound high of 369 She has friends over, getting ready, nails, makeup, hair up doo, and the excitement of the night. Excitement causes lows. I am hoping she is okay, she is suppose to text me when she does her next check. What changed recently? Exercise, gym class for the past 2 weeks lower her TDD from average of 59 to new average of 40.... This new number managed to change everything. The average is from the past 7 days. Going to be a long night, hope she is having fun!
