How ridiculous, Mrs A has a wealth of knowledge. And that's appropriate to share. It's part of the Body of Christ working together, every part contributing what it can. Mrs A, having raised all your kids, could contribute a lot in the realm of childcare, and what was an appropriate cause for concern and what was "normal" for a kid growing and developing. There were so few people with kids at that time, most were singles. I'm sure that later, F was able to advise and guide some of the others who later had kids, and that's nothing specially "spiritual."
In fact, that's a significant reason why TWI failed. Didn't meet people's needs, kept them in enforced infancy and dependence, didn't allow natural growth in personality and development in changed circumstances, etc etc. God gave us common sense for a reason and TWI was out to destroy that as "senses knowledge" and replace it by its own "mystery religion."
So thankful we're all out.
