We had many problems in the beginning with bad pods or beeping pods. We got quite a few of those beeping “bad” pods that they have since gotten rid of but it was pretty discouraging in the beginning. We hung in there thought and still really like the OmniPod. I think it takes a while to figure out where the best spots are for absorption. My son just turned 3 and has been on the pod for a year. The best spots for him are the back of the arms. We used the top of his butt for a long time and found that right after changing a pod - it took a while for it to kick in. Make sure that when you put on a new pod, you pinch up the skin. Then give yourself a little bolus - we do 0.05 bolus if his BG is normal. If he’s high, we do the correction and then I up his basal by 10-15% for two hours. This normally takes care of the highs that we experience when we do a pod change. I’ve spoken to our Endo about this and he says some people normally go high right after a site change, they don’t know why but suspect that the body is rejecting the cannula, etc
Regarding having the pod work for three days - for some people, it just doesn’t. We normally get 2.5 days out of our pods. Due to the rough and tumble life of a 3 year old, our problems are more about the adhesive pulling away from the pod than the pod failing and not working. If you find you are going high 12 hours before your supposed to change, try changing it at the 2.5 days mark and see if that helps. I think the whole reason you want to change the pod every three days is because the body naturally will start to reject the cannula and the absorption may start to not work. That said, a bit about absorption that I’ve learned - some spots are just not great. Others may be fine all the time and then you accidentally put the cannula in a muscle and then you get little or no absorption. If Will runs continues to run high for 8 hours or so after a pod change, I just give in and take it off and try another spot. The pod won’t beep because it has no way of telling you that it’s in a muscle.
I have always called customer service whenever I experienced a beeping pod or a bent cannula. If you get an alarm, call them, they will tell you what it is, etc. I called a lot in the beginning. They are very helpful and can tell you what you need to do regarding insertion, etc.
