@rutgersmamma , the NFP class became a requirement in my parish maybe 8 years ago. It’s based on temps and discharge and other fun things. Taught by trained practitioners. There was a whole group of folks who decided that it was the right thing to do and persuaded the pastor at the time to go along with it. Most of them had several children all stairstepped about 18 months apart, FWIW. Happy it wasn’t a requirement 30 odd years ago.
