We have been struggling with this problem for a little while, and it is starting to get very frustrating. My son is an extremely active 5 year old. We started pumping in July and frequently rotate pump sites - stomach, love handles, bum.
We use the Inset infusion site 6mm with the Animas Ping, and pump with Humalog. For some reason around the 36 hour mark the infusion site just stops working, and lately we are lucky if we get 24. Pump sites aren't cheap and I am pulling my hair out trying to figure what the problem is. I'm not using one spot over and over, the sites aren't kinked, he doesn't have any irritation at the site when I remove it. I just can't figure it out - if it is the insulin, or the type of infusion set we are using. I talked to the doctors office about it and they were not very helpful just encouraging me to use more areas, which I already do, or to try inserting the infusion set through Tegaderm (I'm not quite sure why this would help - anyone who's had experience I would love to hear it).
So I am hoping to hear advice from anyone who has had the same problem - if your infusion sets quit working why was it, and what did you do to fix it?
I read somewhere that children's bodies tend to heal faster and thus reject the site faster, but I haven't found anyone's experience on that either. If anyone has any experience with this I would appreciate your advice. Thank you!
