It's really not a good reason, nursing homes and assisted living facilities are full of old people who rarely get visitors. And, if you talk to nursing home staff, you'll realize that the lack of visitors is true for most of the residents.
I like kids. They are expensive and massively time-consuming. They are as wonderful as they are stressful. But most kids grow up to be ungrateful shits, I've met many an adult who bitched constantly about their parents, who were in no way abused or neglected. In most cases, in fact, it was evident through their discussion that the parent probably erred towards spoiling them. Which isn't exactly good parenting, but also not exactly the worst crime in the world.
