My daugther was dx July 19th. We expect that dr will write for a pump at next appt. I think I understand the basics about a pump but I have not been able to grasp the CGSM concept very well. Can someone give me the basics on it, or recommend a link with basic info. I read through several postings here, but they all assumed that I knew more than I do. Thank you! I'm wondering if a CGSM is something we need to be asking for when we discuss the pump this month. PS My daughter is 8.
