I remember feeling the same way. However, my D was in her teens. Much harder when they're so young. My D was so brittle they couldn't keep her sugars controlled. She was in the ER almost every weekend. The best thing to happen for her was when she was put on an insulin pump. I believe her life has been extended due to the pump. If your doctor has not suggested it, read up on it and ask him if it would be the route to take with your little one.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
