My kiddos were 13.5 months apart (I was two weeks "late"). I ended up with a c/s after an induced TOL. Neither of the vbac supportive docs I saw were concerned about how close the births would be.
Wife to Joe. Proud, tired mommy to Captain Destructive (6/09), Sir Screams-a-lot (8/10), and another little miracle due 3/13.
Trusting God brings life. Believing brings rest.
