Good morning! It looks like squishy is doing really well. It's great to hear that the testing and shots are getting easier, it does take a little practice to get the technique down. It definitely looks like you are on the right track!
It would be great to get some +7 and later #s if you can, I see on your SS that your DH will try to get some today. That will help you figure out when the nadir is, and how low he gets. When you have a chance, you should also try to do a curve or a mini curve, that would give you a more complete picture of how the insulin works for him. I know that can be hard to fit into busy schedules! Sorry if someone else has already suggested this to you, I haven't been reading all of the threads because I'm still in the learning process myself.
Good for you that you and your DH are both testing and shooting! I'm in the process of teaching my DH, he's not really comfortable with medical-type stuff.
