Hi and welcome. I am sorry for the dx. BF can help a bit with the anxiety of a dx, for the child. That's what I think anyway. With help from your diabetes team, I am sure it will be doable. Although reading about possible causes of T1 D is certainly interesting, I think it's a process we all go through, trying to find the why of something. But it is what it is, and nothing you have done would have prevented it. ETA - you can begin pumping at any age.
