Seperate insulins that are normally mixed together for a shot

My daughter get a "mixed" shot of Humolog & Novoli N in the morning adn seperate shots of Humolog & Lantus in the evening. She wants to spend the night with her grandma but her & her grandma have not been able to get the hang of mixing the morning shot. They do fine with the single insulin shot. I need to know if the morning shot can be done with 2 seperate doses and if so, does the dosage need to be adjusted.

I am a long-time type 1 diabetic who has taken all of these insulins at different points in my life. It should not matter whether her grandma gives her two separate shots or mixes those two insulins in one shot. The only insulin that I am aware of that cannot be mixed with others is Lantus -- it ALWAYS must be given as a separate shot. But the other insulins can be given by themselves or mixed. It shouldn't change a thing. The reason that they are usually mixed is so the diabetic person only has to have one shot rather than two. Giving them separately should not change the dosage in any way. It is wonderful that your daughter can have this special time with her grandma.
