It could be that the insulin and the food is finally started to work with his body and he is improving. Nice to see!
My no shoot number for new diabetics is at least 180, so I think I'd plan to skip. He will likely be high tonight as he will have been 24 hours since his last shot, but yes, i would still reduce. Your last dose gave you an unshootable pre shot and maybe a low overnight nadir. Sounds like he'd like less insulin! Maybe .5 tonight. You can always raise it tomorrow if it's stays too high.
Good news. Good job for both of you.
