i hade 2 c-sections almost exactly 2 years apart. (one born feb 12, 2005 and the other feb 6, 2007). it seemed ok to me. personally, i wouldn't want them any closer together. but others love having it all "over and done with" sooner. i would consider a third, but it would not be as soon after as my second was. i'd maybe try to have 2.5 years between them.
