After a rather lively debate on the group wall, I figured I would get us started here (which may be a better platform for any further discussions)
I am a father of 4 with our 5th blessing joining us in November. I am a recent convert to Catholicism, but have been studying it for some time. I am currently working on an MA in Theology and serve on active duty in the Coast Guard.
Post baby, it looks like we will be going with the Sympto-Thermal Method which is advocated by the Couple to Couples League (CCL)
