After doing the nightly tests at 1:00am and 3:00am I decided that I would decrease Connor's basal rate at those times because he was low 2 nights in a row. Yesterday before he went to bed I made the changes. I was very tired, I had a headache and his older siblings were not helping matters. My husband is working in Bahrain right now and I was also feeling lonely with the long weekend. I wanted to decrease the rate but, I went up by .025. I woke up at midnight breathing heavy, not sure why and then the image of the pump and the number slammed into my mind. I rushed into his room and tested him he was 51. I grabbed a soda and had him drink half, I knew he wasn't done dropping. I grabbed his pump and checked the basal rates and I had indeed hone the wrong way. I corrected my error and went to my room and cried. When I retested he was 159. He ws 139 at 3;00am and 119 at 6:20am. I am thankful everything was ok but, I am so angry with myself for the mistake. Once when he was on MDI I drew out Lantus instead of Novolog when I ws overly tired. I freaked out when I called the Endo. After that I had alway told myself, "Don't dose insulin tired." he could have been hurt and it would have been my fault.
