Dearest and I talk about this a lot. We just had our first interview with my local church. The deacon was very delighted to hear we intend to follow church teaching on this.
Good for you and Dearest. The use of NFP to avoid pregnancy can be a struggle, but compared to the alternatives ... egad! Besides, starting a family at your stage of life, I'd think "avoidance" is the last thing on your mind :-). There is nothing more enjoyable than a Personal Relationship during your ovulation. The Urge to Merge is an unfailing indicator of fertility, at least in my experience - I even note it on my NFP charts, when I'm bothering to chart! Gosh, what was God thinking?
