My daughter is on the OmniPod and wants to switch to a tubed pump (either MiniMed or Animas). She gets very itchy rashes that linger for many days with the Pods. Any advice for her from people who have switched? I'm afraid she will switch and then she wants to switch back. Obviously i will let her know if we switch, it is for a good amoutn of time. Anyway, advice would be greatly appreciated.
