Lantus is given 12 hours apart.
I see that you are doing Trey a few times a day.
You could be giving her too much insulin.
I do not see prvious posts from you, if there are can you link them to this thread.
It would help if you are able to get your ss working as well as a profile for Trey.
Please go over to the Lantus board and read the "stickies" at the top and see how Lantus should be dosed.
