I think my petsitter was overwhelmed by Rudy's care.
She didn't grasp the idea of the half unit marks, so it looks like she'll just be giving him 1 unit for 2 cycles. I did send her home with an old pen and both kinds of syringes so she can get used to drawing the insulin. Hopefully, she'll also figure out the half unit marks too so he can get closer to his anticipated regular dose. I'll leave a syringe filled with punch so she can see what/where she needs to draw too.
And I guess I'll be typing even more detailed instructions than I thought I needed...
