VBA2C

For the moms who had VBA2C what was the age gap between your last c section baby & your VBAC baby? I've had 2 c sections & really DO NOT want another one. But I know if you get pregnant too soon after your section you have to have another. Me & my SO want more kids but we are waiting until I'm in the clear. All the way in the clear. I'm also trying to decide what year birth control to get. (IUD)
