CSection Incision Open

I have a 3 month old son and this is the 3rd time my inciospm has opened. The first time I thought it was infected, I had my ob check it out and he told me it was just irritated. Well, a week later on both ends of my incision were open, just far enough to where you could see in. The one side closed up and I ended having to go back 2 more times for them to put steri strips on it to close it. The last time i went it WORKED, the strips closed it up. Well now the one side is open again, deep enough I could stick the head if a q-tip in it. I called the ob around last Thursday and they told me to see if it closes back on it's own and it's just not. 🙄☹ I'm calling the OB tomorrow but has anyone else had this problem? Does it close and stay closed?😫
