In your recent answer about mixing insulins, did you meuld like to try that because our 5 year old son often has high midmorning blood sugars even though we give his R and N half an hour before breakfast, and we have decreased his breakfast and eliminated fruit from it. It makes sense to me to replace some of his morning Regular with lispro to get better coverage of breakfast, but to keep some of the R because that's helping cover his lunch.

What do you think? Of course, we would discuss it with our endocrinologist too, but he doesn't have much lispro experience yet.


Yes, you can mix the two insulins to try to achieve the effect you describe. However, you should give the injection right before breakfast because lispro insulin [Humalog®] acts in ten minutes and with a 30 minute interval you would run the risk of hypoglycemia. You may find, in fact that the injection can be given immediately after breakfast which allows you to take both the pre-meal glucose level into consideration as well as your son's appetite. Be sure to let his doctor know what you plan to do and make the change gradually.
