| I am 21 now and I don't log my blood sugar either and I never really did- my mother always did it for me until I took control of things as I got older. I've made a promise to myself to start writing things down- it is the only way to see what insulin dose is working best.
But I do always carry my insulin with me everywhere and I test my blood sugar as often as possible. As long as you can make sure she tests her blood, then you can write down her numbers for her because most monitors keep a record of the last 20 times she tested with the time. When I was 15 I was out of control with my blood sugar and I could have caused damage had I not grown out of that phase of my life. I also switched to lantus at 15 and it saved me because I had to worry so much less about fluctuating blood sugars throughout the day. I never wanted to wear a pump because at 15 it didn't fit in with my wardrobe! But tell your daughter that testing her blood sugar is so extremely important for her not to have poor control later on in life. I was also very embarassed to tell my friends at that age that I was a diabetic which I think was a mistake. Encourage her to inform her friends- I found that when i did begin to tell my friends they either didn't care or were supportive- no one will think negatively of her for it-
The best advice I can give is don't let her control things herself unless she is going to make an effort to do it properly-an example being if she wanted to stay out until a certain time tell her she can't unless she is going to test her blood- even if she hates you for it- she will thank you when she gets older- I didn't understand how hard it was for my mother at that age but I do now and I really appreciate it  |
