I agree that hoping for an intelligent and physically healthy child definitely reflects an ableist worldview. This is basic disability/crip theory.
For those who are going to argue: wanting an intelligent child is ableist because it implies that people who are intelligent have more worth than people who are not. It’s assigning the value of a person based on a pretty narrow and Western conceptualization of how people think. A person is valuable not because of their intelligence, but because of their existence — all are equally valuable because they’re people, and everyone is equal. The same goes, believe it or not, for physical disabilities, including health. If you disagree, then you think that not all people are equal, which is problematic, as problematic as hoping that your child is straight, or male, or has blonde hair and blue eyes.
