My aunt DID discipline her child and she turned out well. But she turned to mush with her dogs. And the older she got, the less she said "no" to the dogs she had. My cousin summed it up perfectly. Her mother equated training and discipline with being "mean" to the dog. Anything that inhibited its widdle fwee spiwit was just awful. I see this in a lot of older people and their pets. But it sounds like your stepmom was never much of a disciplinarian.Yes, and I didn't know SM until I was an adult and her children were adults. Based on their life trajectories, I don't think that she disciplined her children either. One child is a disaster, one is very successful and has very little to do with SM. This child loves her but lives across the country and interacts very little. I don't know the disaster child. (They are both middle aged)
Maybe if she sees that one visit without the dog can go well and the dog survives just fine, there can be more. Fingers crossed.
