First thing this lady needs is a “mindset reset” and some reality checks. She’s a mom...she needs to be a momma bear!
Get her a copy of Jeff Cooper’s timeless classic “Principles of Personal Defense” and tell her to read it. I made my daughters read it. It is a short, concise read. It is excellent!
