Can you tell us about Saturday? I see the 51 on the ss - on a human glucometer that was ok. I think it shows you were using a human meter then. Normal numbers are considered to be 50-120 on a human glucometer, so you didn't almost kill him. Don't worry one bit. You got a lower test than you're used to and you took action - that was all appropriate. You're doing a good job with him, Sarah.
Since you're following SLGS, it calls for a reduction when you catch a test under 90. That would mean that after the 51, you would reduce his dose to 0.75u.
