My 12 yo son chose to use Lantus instead of his pump for basal. He is on a school and travel baseball team and the pump site gets clogged with sweat, dirt, pus even with frequent changes. Just doesn't work for him as a basal, though he uses it for boluses. He has been high every afternoon at practice which impacts his performance. We have been playing around with his carb ratios and correcting highs but it doesn't help. He also has been eating lower carb to lose a little weight, so he needs less bolus anyway. I think the problem is his basal from a nighttime cose of Lantus wearing out. Could that be it? He gets his Lantus st 9pm and is low in the middle of the night and wakes up high - high 200s. Most days lately, we have trouble getting it back down. Should we try 1/2 dose Lantus with bedtime snack and 1/2 dose with breakfast? Has that made a difference for anyone?
