I agree with you, but I think you're talking about something different than Bloom was discussing. She isn't referring to telling our daughters and nieces that they are beautiful. She is talking about meeting a little girl for the first time, and complimenting her appearance, and leaving it at that.

We can give little girls we've just met a huge gift by showing them that we are interested in their brains FIRST. Then, when we know them better, we can shower them with "you're so beautiful"s in between the "you're so smart"s.
