Hi, I was just checking in before bed and saw your post. It doesn't look like you've shot a number this low and Samwise is new to the Lantus. I wouldn't shoot cause you don't have the data behind shooting these numbers. HOWEVER - if you have not yet feed and you have not yet shot - you could delay and test again in 1/2 - 1 hour. If the number is rising "enough" then you could potentially shoot. Remember - that is only if you haven't fed. Otherwise the rising number probably is just food starting to spike. If you have already decided not to shoot and have fed him - mark it on the SS and see how the numbers look tomorrow.
Another option would be to shoot a "big chicken **** dose" - but again I would only do this if the number was rising ANd you hadn't fed him AND you were going to be up to test more tonight. This type of dose is reduced dose - in your case say, .5 unit. AGAIN - if you are shooting - you must be up to test him tonight. Hopefully you are also prepared with HC foods, lots of test strips and coffee for yourself.
Options - but don't know when you actually posted this and when your shot time is. Probably best to pass on the shot tonight......
