I am looking for a Crime/Thriller/Suspense/Mystery American movie that was produced in the 70s or 80s or 90s. The Plot: a young couple who lives with their kids and dog in a nice house. One day an elderly lady comes to visit them claiming to be related to the wife. The couple naively believes her and allows her to move in. Overtime, she starts to subtly, cunningly and stealthily try to kill each of them including the dog. I cannot recall the cast as I was young when I watched it. I thought the title was, "The stepmom/mother;" however each time I google it, I end up with a Julia Roberts movie. Can someone please remember this movie and its title?
