Yay Mummatotwo!!!!
Just to let you know - it definately is a crock! My births will be 16.5 mths apart so I fell pregnant only 7-8 mths after my c/s and my hospital is happy for me to attempt my VBAC. There is a "slightly" increased risk if you are attempting a VBAC prior to an 18 mth gap due to letting the scar heal (I fall short by 1.5 mths!) but the increased risk in almost all cases is not enough to warrant a repeat c/s.
