Usually site changes are a non-issue anymore. We are using the Mio inserter and put numbing cream on for about 45 minutes before hand. However today when I put it in my sweet little 2 year old looked over with big eyes and instantly started crying saying "get it off". I held her until she settled down and went to get the baby oil to remove the old site. When I looked at the new site it had filled with blood. So instead of removing the old one I took off the new one and rehooked to the old one. It was nap time so I'll have to put another site in when she wakes up. But can anyone explain what happened? How to avoid it happening in the future. It just makes me sick to hurt her like that! And then to have to do it again in a couple hours --ugh!
