So we are trying to finalize our pump choice. I do love the simplicity of the omnipod and no tubes to deal with. However, the rep. came over to our house and put a demo on my son and by night-time it was coming off. My 7yr. old is very active (and I know a lot of other kids are too). He is constantly running, tumbling, skateboarding - you name it. I have no idea how it came off. He was brushing his teeth that night and I noticed it kind of hanging there. I asked him if he knew. He claims his brother tugged at it, but my older son denies this. Anyway, kind of disappointed that our first "demo" try at this was a failure. Do people tape over it to secure it better? Also, he had it placed on his arm (sort of on the underside where the rep said it wouldn't bang into things). Would we have better luck on a different site?
